Changes in State

There are 3 states of matter in water. They are Solid, Liquid and Gas. You can learn about them by clicking in the links to the left. On this page, you can find out how one changes to another.

Gas to Liquid

When a gas changes to a liquid, it goes through the process of Condensation. This is when the gas cools and loses energy. Then the particles are forced to change state, from a gas to a liquid.

Liquid to Solid

When a liquid changes to a solid, it goes through the process of Freezing. This is when a liquid cools below the freezing point and loses energy. Then the particles are forced to change state, from a liquid to a solid.

Solid to Gas

When a solid changes directly to a gas, it goes through the process of Sublimation. The particles are forced to change state.

Liquid to Gas

The process in which a liquid changes into a gas is called Evaporation. When a liquid gains enough energy, it can overcome all of the attracting forces. Then it changes state, from a liquid to a gas.

Solid to Liquid

The process in which a solid changes into a liquid is called Melting. When a solid gains enough energy, it can overcome some of the attracting forces. Then it changes state, from a solid to a liquid.

Gas to Solid

When a gas changes directly into a solid, without going through the liquid state, it is called Frost Formation.
