a: Write down the relation between the specific heat at constant pressure and the specific heat at constant volume for ideal gases. Write down the definition of the specific heat ratio. b: Explain the reason why the specific heat at constant pressure is bigger than the specific heat at constant volume. c: Obtain the specific heat ratio for monatomic gases in terms of the degrees of freedom. d: Obtain the specific heat ratio for diatomic gases in terms of the degrees of freedom.
