Solution
Explanation:
According to the P-V diagram provided in the question, P increases as V decreases at a constant temperature. So, it is Boyle's law. So, the temperature will remain constant in the TP graph and pressure will be higher at stage 1 than at stage 2.

In which of the following processes, beat is neither absorbed nor released by a system?
Assertion: Equal volumes of monatomic and polyatomic gases are adiabatically compressed separately to equal compression ratio `("P"_2/"P"_1)`. Then monatomic gas will have greater final volume.
Reason: Among ideal gases, molecules of a monatomic gas have the smallest number of degrees of freedom.
