Which of the following is true for an isothermal free expansion of an ideal gas?

A

`q =0`

B

`w =0`

C

`Delta H = 0`

D

All of these

Text Solution

Verified by Experts

The correct Answer is:
D

In free expansion, w = 0 because Pext = 0
`Delta U = q + w`
`Delta U = 0, w =0`
`implies q = 0`
So,` Delta H = 0`
