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 the figure. Which of the following order pressure is correct for this gas?
1
p1 > p2 > p3 > p4
2
p1 = p2 = p3 = p4
3
p1 < p2 < p3 < p4
4
p1 < p2 = p3 < p4
