Question

PV vs P graph for a gas at constant temperature is
(A) Hyperbolic
(B) Parabolic
(C) a straight line passing through origin
(D) a straight line parallel to X – axis

Answer 1

Answer:

a straight line passing through origin

Answer 2

(D) a straight line parallel to X – axis

Explanation:

At constant temperature, the relation between pV and p will be constant for an ideal gas. The pV versus p graph will be a straight line parallel to x axis. Please refer to the attached picture for the graph.

In the graph, we see that at constant temperature the pV vs p plot is not a straight line for real gases. There is significant deviation from the ideal behavior.
