Thermal Energy and Heat Review

How is temperature related to heat?

• Adding heat energy to an object can increase its temperature.

• Heat energy will flow from objects with a lower temperature to objects with a higher temperature.

• Temperature and heat are two different ways to measure the same thing.

• Heat is the measure of the average kinetic energy of particles in an object.

Eric places some room-temperature strawberries into his freezer. Which of the following choices correctly describes what happens to the strawberries?

• The heat from the strawberries is transferred to the freezer and causes the strawberries to freeze.

• Some of the cold from the freezer is transferred to the strawberries and causes the strawberries to freeze.

• The temperature of the freezer remains the same as the temperature of the strawberries decreases.

• Heat is transferred from the freezer to the strawberries and causes the temperature of the strawberries to decrease.
