### About chapter Chapter 27 - Specefic Heat Capacities of Gases :

SPECIFIC HEAT This is called ‘Heat inertia’ of a substance. Definition : The amount of heat needed for an unit increase in the temperature of unit mass of a (substance solid, liquid or gas) is called it’s specific heat

Unit : kilocalorie/kg-ºC   or   calorie/g-ºC

1 Kcal/kg-ºC = 1 cal/g-ºC

(i) Generally two types of specific heat are mentioned for a gas -

(a) specific heat at constant volume (Cv)

(b) specific heat at constant pressure (cp)

(ii) These specific heats can be molar or gram, depending on the amount of gas considered to define it

• THERMAL CAPACITY OR HEAT CAPACITY   Amount of heat needed to increase the temperature of a substance (any amount) by 1ºC is called thermal capacity of that substance.
