MCQ
If during an adiabatic process the pressure of mixture of gases is found to be proportional to square of its absolute temperature. The ratio of $C_p / C_v$ for mixture of gases is .........
- ✓$2$
- B$1.5$
- C$1.67$
- D$2.1$
✓
Answer
Correct option: A.
$2$
a
(a)
(a)
$P \propto T^2$
$P T^{-2}=$ constant $\quad$ compare with $P T^{\left(\frac{\gamma}{1-\gamma}\right)}=$ constant
$\frac{C_P}{C_V}=\gamma=2$
