1. Solids (e) Definite shape and a definite size. In solid state shape, size and volume is fixed because particles in solids are tightly packed. 2. Evaporation (a) Surface phenomenon Evaporation is the process of conversion of water into vapours. It is a surface phenomenon. 3. Ice crystals (d) frost A deposit of small white ice crystals formed on the ground or other surface when the temperature falls below the freezing point is called as frost. 4. Sublimation (b) dry ice It is a process in which a substance changes directly from a solid to a gas without going through the liquid phase. 5. Condensation (c) dew drops Dewdrops are often found on a spider's web early in the morning after a cold night. Water that is present as a gas in the air cools down and changes into tiny drops of liquid water on leaves and windows. This change from gas to liquid is called condensation. Column A Column B 1.
