Question

A certain mass of a gas is compressed first adiabatically, and then isothermally. In both cases, the initial state of the gas is the same. Is the work done `W_(1)` in the first case greater than the work done `W_(2)` in the second case ? Explain.

Answer 1

Yes, because the area between curves 1 and trhe V-axis is greater than that between curve 2 and the V-axis and the work done is given by the area between the `p - V` curve and the V-axis.
