Heat up a liquid and it becomes a ...?

Explanation:
When a liquid is heated, its particles gain kinetic energy and move faster. As the liquid reaches its boiling point, it undergoes vaporization and becomes a gas. In the gas state, there is no fixed shape or volume and it will spread out to fill the space available. If heating continues, it stays as a gas rather than turning back to a solid or liquid. Plasma would require far higher energy to ionize the gas, not just heat a liquid to a boil.
