If one mole of an ideal gas (C(p.m.)=(5)...

If one mole of an ideal gas `(C_(p.m.)=(5)/(2)R)` is expanded isothermally at 300K until it’s volume is tripled, then change in entropy of gas is:

A

zero

B

infinity

C

`(5)/(2)R ln 3`

D

`R ln 3`

Text Solution

Verified by Experts

The correct Answer is:
D
`DeltaS=nRln.(V_(2))/(V_(1))=1R ln.(3V)/(V)=Rln3`
