@Nithesh Borkar.
Can you please explain how pdv is not zero although dw (work done) is zero?

Free expansion means no pressure from the outside. So w=pdv, here when p= 0. Thus w=0.

Work done in free expansion process is zero because of there is no any boundary.

There is not at all boundary available at either side so it is zero.

In free expansion process enthalpy constant so work done is zero.

Then what do you mean by expansion if it constant volume?

How PdV?
I think here volume change is 0.
