Question 12 • ISP ONLY: Chemistry S2 Q3000XX

Which energy changes are associated with a liquid freezing?

Answer

A

Energy is released as potential energy increases.

B

Energy is absorbed as potential energy increases.

C

Energy is released as potential energy decreases.

D

Energy is absorbed as potential energy decreases.

Explanation

When a liquid freezes, its particles become more ordered and move into a lower-energy arrangement, so their potential energy decreases. The excess energy is released to the surroundings as heat. Therefore, the correct choice is “Energy is released as potential energy decreases.”
