Answer 2

Correct option is
A
a straight line parallel to the pressure axis
For a given mass of gas at a constant temperature, the plot of PV against pressure is a straight line parallel to the pressure axis. This is because PV remains constant with P.

The ideal gas equation is PV=nRT. At constant temperature, nRT=constant. Hence, PV= constant.

Hence, the correct answer is option A.
