A monatomic gas at \(630 \mathrm{~K}\) expands adiabatically to 27 times its initial volume. The final temperature of the gas is
- A \(30 \mathrm{~K}\)
- B \(130 \mathrm{~K}\)
- C \(170 \mathrm{~K}\)
- D \(70 \mathrm{~K}\)
Answer & Solution
Correct Answer
(D) \(70 \mathrm{~K}\)
Step-by-step Solution
Detailed explanation
For mono-atomic, \(\mathrm{f}=3\) \(\gamma=1+\frac{2}{\mathrm{f}}=\frac{5}{3}\) For adiabatically \(\mathrm{PV}^\gamma=\) constant…
