When you add a large amount of thermal energy to water, what happens to the water?

• The water molecules lose kinetic energy and become a solid.

• The water molecules gain kinetic energy and become a gas.

• Thermal energy does not affect water.

• The water will go through a chemical change.

Thermal energy is removed from a sample of helium gas. All of the following are true EXCEPT...

• The temperature of the helium gas will decrease.

• The kinetic energy of the helium gas will decrease.

• The molecules of helium gas will become more packed together.

• The total energy of the helium gas will increase.

What is temperature?

• Temperature is the average kinetic energy of a substance.

• Temperature is the total thermal energy of a substance.

• Temperature measures how well heat can transferred.

• Temperature measures the malleability of a substance.
