Unit 2: Thermal Energy and Heat Transfer Test

Ms. Webber forgot her insulated travel mug and brought a regular coffee mug to school. She misplaces her mug and decides to reheat her coffee during Block 2. Explain what happens to the molecules of the coffee when they are heated.

• The molecules move slower and get closer together.

• The molecules move faster and get farther apart.

• The molecules stop moving completely.

• The molecules change into a different substance.

You injure your ankle playing football at recess and ask the nurse for an ice pack. If you place the ice pack on your ankle, how does the temperature of your ankle change and why?

• The temperature increases as thermal energy moves from the ice pack to your ankle.

• The temperature decreases as thermal energy moves from your ankle to the ice pack.

• The temperature stays the same because no energy is transferred.

• The temperature increases because the ice pack adds heat.
