Question

1 moles of diatomic gas at 27°C is heated at constant temperature, so that its volume is doubled. If R = 8.3 J/mole/K. Find the work done in this process

Moderate

A

1718 J
B

1500 J
C

1640 J
D

2490 J

Solution

$\begin{aligned} dW & = n R T \ln (\frac{v_{2}}{v_{1}}) \\ = 1 \times 8.3 \times 300 \ln (2) \\ = 2500 \times 0.69 \\ = 1718 J \end{aligned}$
