Question

solid and liquid has only one specific heat capacity while gases has two why

Answer 1

in solid particles are closely packed where in liquid are scatters and in gases they are free from capacity

Answer 2

A solid or a liquid when heated, does not undergo any change in the volume or pressure. But in case of a gas, both the pressure and volume change on heating. Therefore, specific heat of a gas is defined either at constant volume or at constant pressure and hence a gas has two specific heats.
