Houses are usually made out of wood to avoid loosing thermal energy. What conclusion can you get from this information?

• Wood is a thermal conductor.

• Wood is a thermal insulator.

• Wood has a high specific heat.

• Wood can't increase its temperature.

How does the thermal energy of the liquid in the larger beaker compare to the thermal energy of the liquid in the smaller beaker?

• The liquid in the larger beaker has less thermal energy than the liquid in the smaller beaker.

• The liquid in the larger beaker has more thermal energy than the liquid in the smaller beaker.

• The liquid in the larger beaker has the same amount of thermal energy as the liquid in the smaller beaker.

• The exact volume of the liquid in each beaker must be known to compare the thermal energy of the liquids.

How does heat affect the thermal energy of an object that is colder than the air that surrounds it?

• Heat decreases the thermal energy of an object as energy moves to the air.

• Heat causes the thermal energy of the object to increase as energy moves from the warmer air to the colder object.

• Heat has no effect on thermal energy, but it increases the potential energy of an object.

• Heat is not related to thermal energy, so it cannot affect the thermal energy of an object.

Kito puts his spoon into a helping of fresh, hot, mashed potatoes as shown in the picture. Which process takes place when the objects come together?

• The temperature of the spoon increases, but its thermal energy does not change.

• Energy in the form of heat is transferred by conduction from the warmer mashed potatoes to the cooler spoon.

• The thermal energy of both the mashed potates and the spoon increase as the energy in the form of heat is transferred between them.

• The average temperature of the spoon does not change.
