One mole of an ideal gas is expanded fro...

One mole of an ideal gas is expanded from a volume of 3L to 5L under a constant pressure of 1 atm. Calculate the work done by the gas.

A

`DeltaE=0`

B

`DeltaH=0`

C

PV is constant

D

`DeltaS lt 0`

Text Solution

Verified by Experts

The correct Answer is:
D
`DeltaU =0` (for isothermal process)
`DeltaH=0`
`therefore pv` = constant `DeltaS = nR ln (V_(2)/V_(1))`
`DeltaS gt 0` for isothermal expansion.
