Explanation:

The curve is an isotherm PV=" constant". So, it must be a horizontal line on a T-P diagram. Among the two valid options, 3) is the one that shows that state marked 2 has a lower pressure, as it should.

Explanation:

The ideal gas law is: PV=nRT in your exercise is T=const. rArr PV=const.
If we write T=(PV)/n and consider PV=const. we can conclude that T=const. So (1),(2) can not be the answer.

Look at the P-V diagram: P_1>P_2 the only T-P diagram that maintain this feature is (3).
