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.

Energy that transfers from one substance to another until the temperatures are equal is called...

• convection

• temperature

• melt

• heat

What is thermal energy?

• conduction

• the total energy of the particles

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.
