Question

# One mole of an ideal gas is compressed reversibly from 100 L to 10 L at constant temperature of 27 oC. ΔS of the isolated system is: (correct answer +2, wrong answer -0.5) 0R×300×ln10010R×300×ln10100R×27×ln10100

Solution

## The correct option is A 0For a reversible process in an isolated system , heat absorbed is zero and hence entropy is zero.
