IIT Jee Problem: The specific heats Cp and Cv of a gas of diatomic molecule.

The specific heats, C_(P) and C_(V) of a gas of diatomic molecules, A are given (in units of Jmol^(-1) K^(-1) ) by 29 and 22 , respectively. Another gas of diatomic molecules , B has the corresponding values 30 and 21. if they are treated as ideal gases, then :

What is the specific heat ratio of diatomic gases ?

What is specific heat of a gas is an adiabatic process?

The specific heat of a gas in an isothermal process is

Can specific heat of a gas be negative?

The specific heat of a gas in a polytropic process is given by-

The specific heat of an ideal gas varies with temperature T as

For a gas R/C_V = 0.4, where R is the universal gas constant and C, is molar specific heat at constant volume. The gas is made up of molecules which are

A : The specific heat of an ideal gas is zero in an adiabatic process. R : Specific heat of a gas is process independent.
