V verus T curves at constant pressures P1 and P2 for an idealgas are shown in the figure,
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?
(a) p1>p2>p3>p4 (b)p1=p2=p3=p4
(c) p1<p2<p3<p4 (d) p1<p2=p3<p4
The pressure P1 at a certain depth in river water and P2 at the same depth in sea water are related as : (a) P1>P2 (b) P1=P2 (c) P1<P2 (d) P1−P2 = atmospheric pressure
