MCQ
Which of the following formulae is wrong
- A${C_V} = \frac{R}{{\gamma - 1}}$
- B${C_P} = \frac{{\gamma \,R}}{{\gamma - 1}}$
- C${C_p}/{C_v} = \gamma $
- ✓${C_P} - {C_V} = 2R$
✓
Answer
Correct option: D.
${C_P} - {C_V} = 2R$
d
The difference between $C_P$ and $C_V$ is $R$, not $2R$.
The difference between $C_P$ and $C_V$ is $R$, not $2R$.
