Question

derive a relation between the two specific heat capacities of gas on the basis of first law of thermodynamics​

Answer 1

Answer:

Relation between CP and CV : Suppose one mole of a gas is heated so that its temperature rises by dT. Since the volume is constant, the gas will not perform external work in accordance with the first law of thermodynamics and the heat supplied will be just equal to the increase in the internal energy of the gas.
