Following graph represents a pressure `(P)` volume `(V)` relationship at a fixed temperature `(T)` for `n` moles of a real gas. The graph has two regions marked `(I)` and `(II)`. Which of the following options is true.

A

`Z gt1` in the region `(II)`.

B

`Z=1` in the region `(II)`

C

`Z=1` for the curve

D

`Z` approaches 1 as we move from region `(II)` to region `(I)`

Text Solution

Verified by Experts

The correct Answer is:
4
On moving from region `(II)` to region `(I)`, pressure tends to zero. So, `Z rarr 1`.
