Figure: Reading and Translating P-V Diagrams
Answer: (4) P₁>P₂

Step-by-step solution

On a V-T diagram an isobar is a straight line through the origin of slope

V/T=(nR)/P.

A larger slope therefore means a smaller pressure.

The line drawn steeper belongs to P₂, so P₂<P₁, that is P₁>P₂.

Why the other options are wrong
