Question

. Maja puts a hockey puck onto ice. After a while the temperature of the hockey puck decreases. What happens to the molecules of the hockey puck when the temperature of the puck decreases?

a. The hockey puck loses heat molecules.

b. The energy of the molecules in the hockey puck decreases.

c. The energy of the molecules in the hockey puck increases.

d. The cold energy of the molecules in the hockey puck increases.​

Answer 1

b. The energy of the molecules in the hockey puck decreases.

When the temperature of an object decreases, it means that the average kinetic energy of the molecules in the object decreases. This happens because the molecules lose energy in the form of heat. So, option b is the correct answer.
