Work done per unit time

Obtain an expression for work done by a gas in an isothermal expansion.

Obtain an expression for work done by a gas in an isothermal expansion.

StatementI: Work done by a gas in isothermal expansion is more than the work done by the gas in the same expansion adaibatically. Statement II: Temperature remains constant in isothermal ecpansion but not in adiabatic expansion.
