उत्तर
INTERCONVERSION OF MATTER:
“Change of state of matter from one state to another state and back to its original state is called inter-conversion of matter.”
The diagram showing the Change of State of Matter:
(a) ICE TO WATER (MELTING): Conversion of a solid into a liquid on heating
e.g. ice to water.
(b) WATER TO WATER VAPOUR (VAPORISATION): Conversion of a – liquid into vapours (or gas) on heating
e.g. water to water vapour.
(c) WATER VAPOUR TO WATER (LIQUEFACTION or CONDENSATION): Conversion of VAPOUR (or gas) into a LIQUID on cooling
e.g. water vapour to water.
(d) WATER TO ICE (SOLIDIFICATION OR FREEZING): Conversion of a LIQUID into a SOLID
e.g. water to ice.
