Select the correct set of statement's :

I. Work done by the surrounding in case of infinite stage expansion is more than single stage expansion

II. Irreversible work is always greater than reversible work.

III. On an ideal gas in case of single stage expansion and compression system as well as surrounding are restored back to their original states

IV. If gas is in thermodynamic equilibrium is taken from state A to state B, by four successive single stage expansions.

Then we can plot 4 points on the P—V indicator diagram.
