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.

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.
