Which of the following are incorrect ?

Options

A. Work done by the surrounding in case of infinite stage expansion is more than single stage expansion
B. Irresversible work is always greater than reversible work. (with sign)
C. On an ideal gas in case of single stage expansion and compression system as well us surrounding are restored back to their original states
D. If a gas in thermodynamic equilibrium is taken from state `A` to state `B`, by four successive single stage expansion. Then we can plot `4` points on the `P-V` indicator diagram.

Answer

A, C, D

Explanation

I-Work done by the system in case of infinite stage expansion is more than single stage expansion.
III. Single stage process is a irreversible process.
IV-We have `5` point on `PV` diagram.
