$$\gamma $$ = 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.
