In an isothermal thermodynamical process, the value of work done by a system is

In a cyclic process, work done by the system is

In a cyclic process, work done by the system is

The thermodynamic process in which no work is done on or by the gas is

The thermodynamic process in which no work is done on or by the gas is

Assertion : For an isothermal reversible process Q = - w i.e., work done by the system equals the heat absorbed by the system. Reason : Enthalpy change (DeltaH) is zero for isothermal process.

A thermodynamic system is taken through the cyclic PQRSP process. The net work done by the system is
