What effects how fast particles transfer energy between them?
Assessment Learning Targets:
HS-PS3-4. Plan and conduct an investigation to provide evidence that the transfer of thermal energy when two components of different temperature are combined within a closed system results in a more uniform energy distribution among the components in the system (second law of thermodynamics).
Learning Target
I can use a simulation to explain factors that determine heat energy transfer between two substances.

Question 1
1.
Which state of matter is the most dense?
Question 2
2.
Which state of matter has the most kinetic energy (speed) in its particles?
Question 3
3.
Hypothesis: Which do you think is a larger factor in heat transfer?
Thermal Equilibrium- Transfer of heat energy from an object with higher temperature to lower temperature until both objects reach the same temperature.
Question 4
4.
Based on the definition of thermal equilibrium above, which is true?
We will now use a simulation to see how heat transfers between two objects that are solids. We can use this to infer how this might work when the objects are in the liquid or gas state.
Question 5
5.
Go to this simulation and set it up as shown in the picture below, then press the reset button and then go.
*If it doesn't let you change the mass, set everything else up, press reset again and it should work
At what temperature was thermal equilibrium reached? How do you know?
Hint: Use the graph to help you
You can click on the graph to get the (X,Y) coordinates
Question 6
6.
Keep the simulation as shown then press the reset button and then go.
How fast did the two objects reach thermal equilibrium?
Hint: Click on the graph to get the (x,y) coordinates to find the exact time
Question 7
7.
Keep the simulation as shown then press the reset button and then go.
What was the temperature change between each object? Explain what you think the negative value means?
Question 8
8.
Set up the simulation as shown then press the reset button and then go.
Which was true?
Question 9
9.
Change the simulation to what is shown below then press the reset button and then go.
At what temperature was thermal equilibrium reached? How do you know?
Hint: Use the graph to help you
You can click on the graph to get the (x,y) coordinates to find the exact time
Question 10
10.
Keep the simulation as shown then press the reset button and then go.
How fast did the two objects reach thermal equilibrium?
Hint: Click on the graph to get the (x,y) coordinates to find the exact time
Question 11
11.
Keep the simulation as shown then press the reset button and then go.
What was the temperature change between each object?
Explain why you think the temperature change was not the same?
