Vaporization is one of the phase transitions that needs additional thermal energy. The kinetic energy of molecules will increase when heat energy is introduced to a substance.
vaporization is the process by which a substance is transformed from its liquid or solid state into its gaseous (vapour) state. Boiling is the term for the vaporization process when conditions permit the creation of vapour bubbles within a liquid. Sublimation is the process of converting a solid into a vapor.
During freezing, a substance's temperature stays constant while the liquid's dissolved particles transform into crystalline solids. Energy is released because particles in a liquid have more energy than particles in a solid.
