An ideal gas

Why does a gas have two types of specific heats?

Why do gases have two specific heats?

Why are the specific heats of gases at constant pressure and at constant volume different? Determine the relation between these two specific heats of an ideal gas.

In gases of diatomic molecules, the ratio of two specific heats is________.

Show that the adiabatic bulk modulus of an ideal gas is equal to the product of the pressure of the gas and the ratio of its two specific heat (gamma) .

Explain the two specific heats of a gas? Show that the difference between two specific heats is equal to the universal gas constant.

Explain the importance of the ratio of the two specific heats of a gas.
