During adiabatic expansion, if the temperature of 3 moles of a diatomic gas decreases by \(50^{\circ} \mathrm{C}\), then the work done by the gas is
(R - Universal gas constant)
- A \(375 R\)
- B \(750 R\)
- C \(1500 R\)
- D \(825 R\)
Answer & Solution
Correct Answer
(A) \(375 R\)
Step-by-step Solution
Detailed explanation
\(C_V = \frac{5}{2} R\) \(W = -n C_V \Delta T\) \(W = -3 \times \frac{5}{2} R \times (-50)\) \(W = 375 R\)
