(a) MELTING: Conversion of a solid into a liquid on heating e.g. ice to water.

(b) VAPORISATION: Conversion of a – liquid into vapours (or gas) on heating e.g. water to water vapour.

(c) LIQUEFACTION or CONDENSATION: Conversion of VAPOUR (or gas) into a LIQUID on cooling e.g. water vapour to water.

(d) SOLIDIFICATION OR FREEZING: Conversion of a LIQUID into a SOLID e.g. water to ice.

(e) SUBLIMATION: Conversion of a SOLID directly in GASEOUS (vapour) state and on cooling directly back to SOLID e.g. Naphthalene sublimes at room temperature.
