Question

What is molar specific heat? Establish relation between them?

Answer 1

Specific heat capacity ⇒ It is the amount of heat energy required to raise the temperature of an 1 kg of body by 1° C.

Molar Specific heat capacity ⇒ It is the amount of heat energy required to raise the temperature of an 1 mole of body by 1° C.

Relation between Specific heat capacity and molar specific heat capacity is given,

       C = Mc, where m is the molar mass of gas, c is the specific heat capacity, and C is the Molar specific heat capacity.

It can be measured at constant pressure or at  constant volume.

When measured at Constant pressure, it is called Cp and when measured at constant volume, it is called Cv.

Relation between Cp and Cv was given by Mayor's, in forms of Mayor's equation,

Cp - Cv = R

Hope it helps.
