When one mole of an ideal gas is compressed to half of its initial volume and simultaneously heated to twice its initial temperature , the change in entropy of gas (DeltaS) is :

Answer»

`C_(p.m) In 2`
`C_(V.m) In 2`
`R In 2`
`(C_(v.m) - R) In 2`

Solution :`DeltaS =nC_(v.m) "In" (T_(2))/(T_(1)) + nR "In" (V_(2))/(V_(1)) = C_(v.m) "In"2+ R "In" ((1)/(2)) = (C_(v.m)-R) IN2`
