Initially the pressure of 1 mole of an ideal gas is \(10^5 \mathrm{Nm}^{-2}\) and its volume is 16 litre. When it is adiabatically compressed, its final volume is 2 litre. Work done on the gas is \(\left[\right.\) molar specific heat at constant volume \(\left.=\frac{3 R}{2}\right]\)
- A 72 kJ
- B 7.2 kJ
- C 720 kJ
- D 360 kJ
Answer & Solution
Correct Answer
(B) 7.2 kJ
Step-by-step Solution
Detailed explanation
\begin{aligned} & \text { } P_1=10^5 \mathrm{Nm}^{-2}, \mathrm{~V}_1=16 \text { lit, } \mathrm{V}_2=2 \text { lit, } \mathrm{C}_{\mathrm{v}}=\frac{3 \mathrm{R}}{2} \\ & \therefore \mathrm{C}_{\mathrm{p}}=\mathrm{C}_{\mathrm{v}}+\mathrm{R}=\left(\frac{3…
