प्रश्न
Explain the term ‘Interconversion of matter’. With reference to ice, water, and water vapour show diagrammatically the change of state of matter from solid to liquid to gaseous and back to the original state.
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.
