Question

why is the molar specific heat of diatomic gas larger than that of a monatomic gas reason

Answer 1

Molar specific heat of a diatomic gas is greater than that of a monoatomic gas as a diatomic gas has more degree of freedom.

In a monoatomic gas there can only be degree of freedom due to translational kinetic energy which can be in 3 planes x,y,z. In a diatomic gas along with this there are 2 rotational degree of freedom too for the reason that the two bonded atoms can rotate about the bond.

Each degree of freedom contributes 0.5R to the Molar Specific Heat at constant volume so that is why monoatomic gas has less molar specific heat at const. vol. than a diatomic gas.

Answer 2

Answer:

because it has more ways to store that energy. only kinetic energy of motion is related to temperature
