Explain the difference between temperature and heat.
From the textbook, the definition of temperature is the quantity that indicates how warm or cold an object is relative to some standard. Heat, on the other hand, is the thermal energy transferred from one thing to another due to a temperature difference.
The temperature of a stove top can range anywhere from 400-600°F. If you were to accidentally place your finger on this hot surface, you will feel the heat transfer from the stove top to your finger. The heat is the thermal energy being transferred to your finger, which is why you feel warmth.
Density
From the article written about density on the website “Teacher’s Domain,” it is easy to understand what density is and how to relate it to different objects. The two examples given on the website which were used to illustrate density were cork and lead. Since lead has a greater weight than cork, it will have a greater density. The same concept holds true for liquids. If liquid A has a greater weight than liquid B, liquid A will have a greater density.

ReplyDeleteOnline Assignment: Density and Buoyancy
I watched the video provided on this website, made from a show I remember watching as a child, ZOOM! I was very excited about this. The girls began their demonstration by mixing blue colored water with corn syrup and then they added oil. The corn syrup, the most dense liquid, stayed on the bottom. Next came the water and then the least dense, the oil, remained on top. Then, they dropped grapes into each cup of liquid to see if it floated or sunk. The grape sunk in the water and in the oil, but stayed afloat in the corn syrup. They then performed the same tests using a plastic building block, a metal nut, and a piece of Styrofoam. These experiments were really cool and super easy and cheap to perform in the classroom. Most importantly, it would be fun and exciting for children to be able to make these observations!
The difference between temperature and heat:
Heat is the thermal energy transferred from one object to another and temperature is the measurement of this transfer - of how warm or cold something is. For example, the freezing point of water, the point at which it will turn into an ice cube, is 32 degrees F. Therefore, when one touches an ice cube, the difference of temperature will cause the coldness to transfer to his/her finger, causing that person to feel coldness.

ReplyDeleteLab for thursday:
ReplyDeleteThis lab was to experiment with finding density. This was easy for me because our project is about density. I weighed the object, then put it in the water. I divided the mass of the object by how many ml it made the water go up and i got the density. It was simple but i think a good learning tool for young children.
Difference between temperature and heat.
Temperature- the amount of hotness or coldness measured on a temperaure.
Heat-a form of energy that is transferred by a difference in temperature
Such as a pan may have a room temperature of 70degrees F but when applyed to a hot stove energy is transpered and heat whatever is in the pan and the pan. This is an increase in temperature.
Thursday
ReplyDeleteThe lab for Thursday was a lab to test the density of an object. The was first done by looking at where the water line was in the tube, drop in the metal piece, and then looking at the new line to see how much the water was displaced. By taking the weight of the metal cube and dividing it by the space it took up I could calculate the density of the metal cube. The was a very interesting lab and it was fun the test differences in measurements with it.
The Difference Between Temperature and Heat
Temperature is the measure of hotness or coldness of an object or substance with reference to a standard value (such a Fahrenheit of Celsius). Heat is the thermal energy transferred from one thing to another due to temperature differences.
Online Assignment:
ReplyDeleteIn this lab we needed to find the density of the object. We measured the object and then dropped the object into 50 ml of water. We found that the object displaced the water another 10 ml. We then took the mass (78.12) divided by 10 ml to find that the density was 7.812.

Temperature is the measure of hotness or coldness of an object or substance with referencet to a standard value whereas heat is the thermal energy transferred from one thing to another due to temperature differences.
Week 9
ReplyDeleteExplain the difference between temperature and heat.
Temperature is the quantity that indicates how warm or cold an object is relative to some standard. Heat is the thermal energy transferred from one thing to another due to a temperature difference. If you want a cup of hot chocolate, the boiling point of water is 100 degrees C. This would be the temperature. However the outside of the mug gets very warm too. Heat is the thermal energy that is transferred from the water to the mug.
Thursday ONLINE ASSIGNMENT
Our online assignment for Thursday was to read a short article about density. The article explained the basics of density for both solids and liquids. While it is easy to understand that a heavier or denser solid will displace a liquid, it is a little stranger to think about a denser liquid displacing another liquid. The first example that came to my mind was water and oil. We did experiments in elementary with those two liquids and observed how they wouldn’t mix.
Explain the difference between temperature and heat: Temperature is a measure of the warmth or coldness of an object or substance, while heat is the thermal energy transferred from one thing to another due to a temperature difference. For example, the reason an object feels hot to the touch is due to the difference between the surface of the object and your own body temperature. The transfer of the temperature of the object to your finger is what makes you feel heat.
ReplyDeleteThursday: Our online assignment in place of class was to read an article about density and how to find density (m/v). For my group's midterm project, we are doing a lab with corn syrup, oil, and water. In order to do this lab, we have had to find the mass of each liquid and divide it by the volume. From that, we made predictions on the order based on which liquids have the greatest and least densities. The lab is very hands-on and the group members have done a fair share of researching, so I feel that density is one concept that I understand the best in this class so far.
The difference between temperature and heat:
ReplyDeleteTemperature is the measure of warmth and coldness of a solid, liquid, or gas. Heat is the thermal energy transferred from one object to another. Something feels hot when it touches your skin because there is a transfer of heat. Temperature is transfered when the contact cause a change in temperature.
Class was canceled on Thursday so we had an online class. We learned about density and how to measure it.
Thursday's assignment was kind of confusing at first but when I played around with the weight and looked at how they figured out what metal we were using it was easy to figure it out. The article taught us about density and told us the difference between solids and liquids.
ReplyDeleteThe difference between temperature and heat: Temperature is the measure of hotness or coldness of substances and is measured in degrees Fahrenhiet or Celsius. Heat is the thermal energy theat flows from a substance of higher temperature ot a substance of lower temperature, measured in calories or joules. You feel heat from fire from the transfer of the temperature to your body.

ReplyDeleteThe difference between temperature and heat is that temperature is a term used to describe how hot or cold an object is to touch, whereas heat is a type of thermal energy that can be transferred from one object to another.
ReplyDeleteFor example, when roasting marshmallows, you start with a metal stick that is at room temperature for the most part. But when you place that stick in the fire to roast your marshmallow, the fire transfers heat, which heats up the metal stick with increases the temperature that you can feel.
For the online assignment on Thursday, we explored finding the density of an object. We had to take measurements of an object and then we placed that object into 50 mL of water. To find the density of that object I took the mass and divided it by how much the water was displaced due to the object being placed in the water. It was a great simulation to explain density!
Difference between temperature and heat:
ReplyDeleteTemperature is the measure of the hotness or coldness of substances, related to the average kinetic energy per molecule in a substance. An example of temperature would be a stove.
Heat is the thermal energy that flows from a substance of higher temperature to a substance of lower temperature, commonly measure in calories or joules. An example of heat would be what a stove gives off. If you touch a stove you feel the heat.
Online Activity:
For the online activity we read a short article about density. The article explained a few likes about density. We learned that there is a way to predict whether an object will sink or float if it in a liquid. An object will sink if it weighs more than what the fluid displaces. An oject will float if it weighs less than the fluid.
Explain the difference between temperature and heat. --
ReplyDeleteTemperature is the measure of heat or coolness of an object. Heat is the thermal energy that flows from one object to another, from a low to a high temperature, or vice versa. An example of would be if you had a steaming bowl of soup and you placed an ice cube in it. The transfer of cold to the heat cools it down enough to eat it.
Thursday --
For Thursday, we had to read an article about density. The article explained density for solids and liquids. For the experiment, we took an object of a certain measurement and dropped it into a beaker of water. We figured out that the density is found by taking the weight of the material, and dividing it by the amount that the material increased the water by.

If you were to place your hand on the hot surface of a stove,the heat will transfer from the stove top to your hand. The heat is the thermal energy being transferred to your hand, allowing you to feel the warmth.
Density
From the article written on the website “Teacher’s Domain,” let me understand what density is and how itn relates to different objects. The two examples on the website used were cork and lead. Lead has a greater weight than cork, so it will have a greater density. The same is true true for liquids. If one liquid weighs more than a different one it will also be more dense.

ReplyDeleteTemperature is the hotness or coldness of an object that is relative to some standard. Heat is the thermal energy transferred from one object to another because of the temperature difference.
Example of temperature and heat would be if a person had a glass of hot chocolate and you put a piece of ice in the hot chocolate and the water molecules in the ice cube gain energy and the ones in the hot chocolate lose energy. This is all measured by the temperature.
Thursday:
We did not have class on Thursday so we had an article to read and do a lab online. The article helped me better understand density. My group is doing our midterm project on density so this helped me better understand it. For the lab we first measured on object on a scale and then we dropped the object into the graduated cylinder. The water increased. We figured out density by dividing the mass divided by the volume(how much the water went up).
What is the difference between tempurature and heat?
ReplyDeleteTemperature is the measure of hotness or coldness of an object or substance with referencet to a standard value whereas heat is the thermal energy transferred from one thing to another due to temperature differences.
Thursday:
We did not have class Thursday so we were to do an online assignment. We were first to read an article that talked about density in forms of solids and liquids and then we did a lab. The lab consisted of measuring the density of objects into water and then measure the amount of water that was displaced.

ReplyDeleteExplain defference between temperature and heat.
Temperature is the measure of hotness or coldness of an object or a substance relevant to a given standard. Heat is the thermal energy that is transfered from one object to another because of differences in temperature.
Thursday:
We had an online class on Thursday. We first read an article about density in solids and liquids. Then we did a lab that consisted of measuring the density of an object by placing it in water and seeing how much water it displaced.
The Difference of Heat and Temperature is as follows:
ReplyDeleteHeat is the total energy of molecular motion in a substance while temperature is a measure of the average energy of molecular motion in a substance. Heat energy depends on the speed of the particles, the number of particles (the size or mass), and the type of particles in an object. Temperature does not depend on the size or type of object. For example, the temperature of a small cup of water might be the same as the temperature of a large tub of water, but the tub of water has more heat because it has more water and thus more total thermal energy. Temperature is not energy, but a measure of it. Heat is energy.
Thursday
On Thursday we found out density through a cool experiment. We had to add a cube that weighed a certain weight after we did that we had to figure out the density of both the water in the cylinder and cube in the water. It took a little while to find out what the density would be but I figured it out. This would be a quick experiment that students could do to help them become more aware density changes when objects are added to water.
Temperature is the measure how hot or cold something is. Heat is the total a thermal energy transferred from one thing to another due to temperature differences. An example of temperature is how something is measured in Fahrenheit or Celsius. An example of heat is when a person touches the flame on a candle, the heat is transferred from the flame to your finger.
ReplyDeleteWe did not have class on Thursday so we were assigned to do an online experiment. We learned about different densities found in different objects. We were instructed to figure out the density of both the water in the container and the cube that we put in the water. It was hard to figure out the density, but I think that I did it correct after googling how to do it.
Temperature is the hotness and coldness of a substance. This is related to the average kinetic energy per molecule in the substance. Heat is the thermal energy that flows from a substance of high temperature to one of a lower temperature. If you place a pot with water in it onto a stove, the heat is transferred from the stove to the pot to boil the water.
ReplyDeleteSince we did not have a class on Thursday we were given an online assignment which was about density. It was a little hard to understand what to do; however after talking with a fellow classmate I got a better understanding. This was for us to figure out the density of the water and the cube as the cube was placed in the water container.
Temperature is the measure of the hotness or coldness of substances, related to the average kinetic energy per molecule in a substance; measured in degrees Celsius, Fahrenheit, or kelvins. An example is the degree that water boils at is also known as a temperature.
ReplyDeleteHeat is the thermal energy that flows from a substance of high temp to a substance of lower temp that is usually measure in calories or joules. An example is when a person touches a hot stove, the heat is transferred from the stove to your hand. Heat always transfers from hot to cold.
Since we did not have class on Thursday, we did an online lab about density. To start off with, we added a cube that weighed a certain weight. After we did that we had to figure out the density of both the water in the cylinder and the cube in the water. This experiment would be fun to do with students and not extremely hard for them to understand.
Temperature is the measure of the hotness or coldness of a substance, related to the average kinetic energy per molecule in a substance. Heat is thermal energy that flows from a substance of high temperatures to a substance with a lower temperature.
ReplyDeleteOn Thursday we did not have class so we did a experiment on the internet where we filled cylinder with water and see what it takes to get the block to float.
Explain the difference between temperature and heat.
ReplyDeleteTemperature is the measure of hotness or coldness in a liquid, solid, or gas. Heat is thermal energy that is transferred from one substance to another. When you sip a hot drink, the thermal energy from that liquid is being transferred to your mouth, so it feels hot.
Online Assignment
The online assignment had us read an article about density in both solids and liquids. After the article we did an online lab involving density. In this lab we measured the density of objects when in water, and measured the amount of water that was displaced.
Thursday:
ReplyDeleteWe had an online assignment, we were to look at this website where we needed to find the different densities of the different metals that were given. We took an object measured it, then dropped it into a beaker of water. From this we were able to take figure out what the density was by taking how much the piece of material weighed and divided it by the amount that the material increased the water by.
Explain the difference between temperature and heat.
Temperature is a measure of the hotness or coldness of a substance. Heat is the thermal energy that flows from a substance of a higher temperature to that of a lower temperature. An example of this would be taking hot tea and placing an ice cube on the outside of it. The thermal energy from the tea will transfer through the cup and melt the ice cube. Therefor flowing from the hot tea to the cold ice cube.
The other piece that we were to watch was a really neat experiment on how three different liquids sit on top of each other. It was really neat watching the different objects that they used to see which was more dense.
