Solution: Click For PDF Version Equation of state of an ideal gas is
where n is the amount of gas in moles, T its temperature, and V its volume. Work done on an ideal gas under isothermal expansion will be given by
In an isothermal process there is no change in the internal energy. The first law of thermodynamics is
As
We have
