During an adiabatic compression, \(830\, J\) of work is done on \(2\, moles\) of a diatomic ideal gas to reduce its volume by \(50\%\). The change in its temperahture is nearly..... \(K\) \((R\, = 8.3\, J\,K^{-1}\, mol^{-1} )\)
- A \(40\)
- B \(33\)
- C \(20\)
- D \(14\)
Answer & Solution
Correct Answer
(C) \(20\)
Step-by-step Solution
Detailed explanation
\(Given:Work\,done,W=830J\) no, of moles of gas, \(\mu =2\) For diatomic gas \(\gamma = 1.4\) Work done during an adiabatic change \(W = \frac{{\mu R\left( {{T_1} - {T_2}} \right)}}{{\gamma - 1}}\)…
