Question
A plot of volume (V) versus temperature (T) for a gas at constant pressure is a straight line passing through the origin. The plots at different values of pressure are shown in Figure. Which of the following order of pressure is correct for this gas?
Options
p1 > p2 > p3 > p4
p1 = p2 = p3 = p4
p1 < p2 < p3 < p4
p1 < p2 = p3 < p4

Solution
p1 < p2 < p3 < p4
Explanation:
t a particular temperature, PV is constant
Therefore, `V oo 1/p`
So, as v1 > v2 > v3 > v4 the order of pressure: p1 < p2 < p3 < p4 .
