Text Solution

Verified by Experts
The correct answer is:
A

From ideal gas equation ∴ ∴

Comparing this equation with

Slope of line i.e.

It means line of smaller slope represent greater volume of gas.

For the given problem figure

Point 1 and 2 are on the same line so they will represent same volume i.e.

Similarly point 3 and 4 are on the same line so they will represent same volume i.e.

But (= ) or (= ) as slope of line 1-2 is less than 3-4.
