Work is the mose of transfrence of energy. If the system involves gaseous substance and there is difference of pressure between system and surroundings, such a work is referred to as pressure - volume work `(W_(PV)= -P_(ext)DeltaV)`. It has been observed that reversible work done by the system is the maximum obtainable work. `w_(rev) gt w_(ir r)`
The works of isothermal and adiabatic processes are different from each other. for isothermal reversible proces,
`W_("isothermal reversible")=2.303 nRT log_(10) (V_(2)/V_(1))`
`W_("adiabatic reversible")=C_(V) (T_(1)-T_(2))`
A thermodynamic system goes in acyclic process as represented in the following `P-V` diagram:
1. For an ideal gas, consider only `P-V` work in going from an initial state

The net work done during the complete cycle is given by the area:

A

Cycle ACBDA

B

`A A_(1)B_(1)BDA`
