Matter can change from one state to another.
Explain the particle movement of evaporation.
if particles in a liquid are heated up, they gain more kinetic energy and move further apart.
Explain the particle movement of melting
If particles in a solid are heated up, they gain kinetic energy and move slightly apart
Explain the particle movement behind condensing
If particles in a gas are cooled, they have less kinetic energy and move closer together.
freezing
If particles in a liquid are cooled, they have less kinetic energy and move even closer together.
