Answer:
By adding heat energy
It changed to gas
Explanation:
A substance whose molecules are moving around each other is a liquid. They are held in shape by very weak intermolecular forces.
For solids, there is no movement because the molecules are held up in a fixed lattice.
Gases molecules moves randomly and independently of one another.
- When a liquid is heated and it gains heat energy, it changes phase.
- A phase change to gas can be predicted.
- This is because there is an increase in the speed of the substances.
