A student gets a cold drink at lunch, but doesn't drink it until after school. They notice it is much warmer. What happened to the molecules in the cold drink during that time?

• The molecules got closer together.

• The molecules got larger.

• The molecules lost cold energy.

• The molecules started moving faster.
