$$\gamma $$ = specific heat ratio of an ideal gas is equal to

A. $$\frac{{{{\text{C}}_{\text{P}}}}}{{{{\text{C}}_{\text{V}}}}}$$

B. $$\frac{{{{\text{C}}_{\text{P}}}}}{{{{\text{C}}_{\text{P}}} - {\text{R}}}}$$

C. $$1 + \frac{{\text{R}}}{{{{\text{C}}_{\text{V}}}}}$$

D. All of the above

Answer: Option D

Solution(By Examveda Team)

The specific heat ratio is given by $$\gamma = \frac{{{C_P}}}{{{C_V}}}$$
Since for an ideal gas $${C_P} - {C_V} = R$$
So, the given all results are correct.
