Check Your Progress
You have returned home from practice and there is a note on the fridge that says:
“There’s pizza in the fridge, reheat in the microwave if you’re hungry.”
You put the pizza in the microwave and pour yourself a glass of lemonade while you wait. The microwave beeps, and you pull the hot pizza out and set it on the counter. As you set the pizza down, you accidently knock your lemonade over. It takes you a few minutes to clean up the mess, so when you finally come back to the pizza, it is cool.
Draw a molecular model of the pizza as it cools. Include a written explanation.
Be sure to include in your model:
An arrow showing overall (macroscopic) energy movement
Air molecules with motion arrows
Pizza molecules with motion arrows
Collisions between the two molecule types
In your explanation, include the following words: collision(s), temperature, energy
