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

1.	Obtain an expression for work done by a gas in an isothermal expansion.
Answer» Suppose 1 mole of gas is ENCLOSED in isothermal container. LET P1 ,V1 ,T be initial pressure, volumes and temperature. Let expand to volume V2 & pressure reduces to P2 & temperature REMAIN constant. Then, work done is GIVEN by
