Question

A student left a sealed jar of water outside her home. Water can be a solid, liquid, or

gas. When she put it outside, the water was a solid. Twelve hours later, the water had
changed phase and was a liquid. What happened to the water molecules?

Answer 1

The water molecules started to move, following the law of atoms. As they were moving, they heated up, changing phases and turning into water molecules from being prior solid molecules
