StatementI: Work done by a gas in isothermal expansion is more than the work done by the gas in the same expansion adaibatically.
Statement II: Temperature remains constant in isothermal ecpansion but not in adiabatic expansion.

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.

Text Solution

Verified by Experts

The correct Answer is:
A
The slope of adiabatic curve is seven times the slpe of an isothermal curve and slope of both is negative. Thus, area under adiabatic curve is smallter than that under isothermal curve.
