One mole of gas under a weightless frictionless piston is at temperature $T$ , with the space above open to the atmosphere. The work to be done to increase the volume isothermally to three times the original is:

Options:

Answer:

Solution:

$W = p_{0} Δ V - W_{g a s}$ . The gas starts at $p_{0}$ , so $p_{0} Δ V = p_{0} \times 2 V_{1} = 2 RT$ and $W_{g a s} = RT ln 3$ . $W = RT (2 - ln 3)$ .
