Part 1: Warm Up

Last time, we explored kinetic energy in the SIM and how it relates to the speed of molecules of a thing. Below are three different diagrams representing the molecules of three pairs of samples. Use your knowledge of how temperature, speed, and kinetic energy are related to help you complete the Warm Up.

In this activity we will continue to gather evidence from the SIM but this time we will use a new feature. You will drag two the samples together so they become in contact with each other.

Reset the Thermal Energy SIM and complete the following steps.

• Add TWO samples of the same size.

• Turn on “View Kinetic Energy” and “View Energy Transfer”.

• Press the + or - buttons to add or remove energy so that one sample is warmer than the other.

Click and drag one sample to the other so they are now touching. It should look similar to this:

• Click “Analyze” and observe what happens.

• Complete questions 2-3.
