Question

The order of expansion in solid, liquid, and gas
(a) solid > liquid > gas
(b) solid < liquid < gas
(c) solid > gas > liquid
(d) solid < gas < liquid

Answer 1

(b) solid < liquid < gas
In solids, particles are closely packed; whereas in gases, particles are loosely packed. Hence, solids have negligible expansion, gases have maximum expansion and liquids have intermediate expansion.
