A sample of a gas expends from volume $V_1{ }^{\prime}$ to $V_2$ The amount of work done by the gas is maximum when the expansion is
  1. Adiabatic
  2. Equal in isothermal and isobaric
  3. Isothermal
  4. Isobaric

Solution

We know that $\Delta \mathrm{Q}=\Delta \mathrm{E}+\Delta \mathrm{W}$ Work done by gas is maximum when $\Delta \mathrm{E}$ is minimum For Isothermal Change, $\Delta \mathrm{E}=0$ So, for isothermal expansion work done is maximum
