Which of the following process is reverse of melting?
Which of the following process is reverse of melting?
The correct option is A Freezing
Correct Option (a) Explanation:- Melting:- The process in which a solid substance changes into a liquid on heating, is called melting. For example- Conversion of ice into water.
Freezing :- The process of changing a liquid into a solid by lowering its temperature (cooling), is called freezing.For example-conversion of water into ice.Hence ,freezing is the reverse of melting.
Incorrect option explanation:- (b) Condensation:- The process of changing a gas or vapours into liquid by cooling, is called condensation.
(c) Evaporation :- The process of changing a gas to a liquid by cooling, is called condensation.
(d) Sublimation :- The changing of a solid directly into vapour on heating, is known as sublimation.For example - Naphthalene balls.
Concluding Statement :- Hence , freezing is reverse process of melting.
