Melting- solid to a liquid The particles vibrate fast and break free from their fixed position Particles in a liquid Particles in a solid
Freezing- liquid to a solid The particles move slowly and begin to take a fixed position Particles in a liquid Particles in a solid
Evaporation- liquid to a gas at the surface level Some of the particles on the surface speed up Particles in a liquid Particles in a gas
Boiling- liquid to a gas below and at the surface level Particles below the surface speed up and break the surface Particles in a liquid Particles in a gas
Condensation- gas to a liquid The particles slow down Particles in a gas Particles in a liquid
Sublimation- surface particles of a solid form a gas Surface particles of a solid speed up Particles in a gas Surface particles in a solid
