MCQ
The ratio of specific heats $(\gamma )$ of a ideal gas is given by
- A$\frac{1}{{1 - \frac{R}{{{C_P}}}}}$
- B${1 + \frac{R}{{{C_V}}}}$
- C$\frac{{{C_P}}}{{{C_P} - R}}$
- ✓All of these
✓
Answer
Correct option: D.
All of these
d
$\gamma=\frac{C_{\mathrm{P}}}{\mathrm{C}_{\mathrm{V}}}$
$\gamma=\frac{C_{\mathrm{P}}}{\mathrm{C}_{\mathrm{V}}}$
and $C_{P}-C_{V}=R$
