In the given (V-T) diagram, what is the relation between pressures P1 and P2?
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
V verus T curves at constant pressures P1 and P2 for an idealgas are shown in the figure,
