Amplify Phase Change

Evaporation is the process where liquid water turns into water vapor (gas) when it gets warm.

Molecules move faster and spread apart as they gain energy from heat.

Condensation is the process where water vapor (gas) turns back into liquid water when it cools down.

Molecules slow down and come closer together as they lose energy.

Melting is the process where a solid turns into a liquid when it gets warm.

Molecules move faster and break apart from their fixed positions.

Freezing is the process where a liquid turns into a solid when it gets cold.

Molecules slow down and arrange themselves into a fixed structure.

A phase change is when a substance changes from one state of matter to another, like solid to liquid.

The three main states of matter are solid, liquid, and gas.
