Process of change of states of matter:
Vaporization-The process of change of water into vapor is called vaporization. When water is heated after reaching at 1000C water starts boiling. At this temperature water turns into vapor.
Condensation-The change of vapor into water because of decrease in temperature is called condensation. Condensation is the reverse process of vaporization.
Freezing-The change of liquid into solid because of decrease in temperature is called freezing. Water change into ice because of decrease in temperature, in other words water freezes into ice because of decrease in temperature. Water freezes at 00C.
Melting-The change of solid into liquid due to increase in temperature is known as melting. Ice, which is a solid melts, i.e. changes into water at 00C.
Sublimation-Sublimation in everyday life:
The dry ice (solid carbon dioxide) turns into vapor without changing into liquid and is considered as sublime. Because of this property dry ice is used to give the illusion of smoke or cloud on the stage in movies and stage shows.
Evaporation-In evaporation, matter changes from a liquid to a gas. In condensation, matter changes from a gas to a liquid. All matter is made of tiny moving particles called molecules. Evaporation and condensation happen when these molecules gain or lose energy
