The pressure \(P_{1}\) and density \(d_{1}\) of diatomic gas \(\left(\gamma=\frac{7}{5}\right)\) changes suddenly to \(P _{2}\left(> P _{1}\right)\) and \(d _{2}\) respectively during an adiabatic process. The temperature of the gas increases and becomes \(......\) times of its initial temperature.\(\left(\right.\) given \(\left.\frac{ d _{2}}{ d _{1}}=32\right)\)
- A \(5\)
- B \(2\)
- C \(4\)
- D \(0\)
Answer & Solution
Correct Answer
(C) \(4\)
Step-by-step Solution
Detailed explanation
\(PV ^{\gamma}=\) const \(\quad d =\frac{ m }{ v }\) \(p \left(\frac{ m }{ d }\right)^{\gamma}=\) const \(\frac{ p }{ d ^{\gamma}}=\) const \(\quad \frac{ d _{2}}{ d _{1}}=32\)…
