StatementI: A gas is expanded from a volume `V` to `2V`, first through adiabatic process then through isothermal process. Work done in isothermal process is more if final state `(i.e.` pressure and volume `)` in both the cases is same

Statement II: Work done by the gas is equal to area under `p-V` curve.

Options

A. Statement I: is true, Statement II is true and Statement II is the correct explanation for Statement I.
B. Statement I: is true, Statement II is true and Statement II is NOT the correct explanation for Statement I.
C. Statement I is true, Statement II is false.
D. Statement I is false, Statement II is true.

Answer

A

Explanation

When final stage in same with same initial volume, the work done in adiabatic expansion is more.
