Kevin puts his spoon into a bowl of fresh, hot, mashed potatoes. Which process takes place when the two objects come together?

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

• Energy in the form of heat is transferred from the mashed potatoes to the spoon.

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

• The average temperature of the spoon does not change.

Answer explanation

Heat always travels from a higher temperature object to a lower temperature object until they are the same temperature!

Reggie puts a beaker of ice and water on a hot plate, and the ice slowly begins to melt as shown in figure below. After a few minutes, only liquid water is in the beaker. Eventually, the water becomes hot and boils. The liquid water changes to water vapor, which is a gas. In what way is the liquid water different from the water vapor?

• The liquid particles move slower

• The liquid has a higher boiling point

• The vapor has a lower temperature

• The vapor particles have less energy
