Solution

The correct option is D
.

Just like a single macroscopic pressure being undefined for a gas which is not in equilibrium, a single macroscopic temperature is also undefined. So the temperature at $P_{1} a n d P_{2}$ need not necessarily be the same, and most likely wouldn't be the same.

The pressure $P_{1}$ at a certain depth in river water and $P_{2}$ at the same depth in sea water are related as :
(a) $P_{1} > P_{2}$ (b) $P_{1} = P_{2}$
(c) $P_{1} < P_{2}$ (d) $P_{1} - P_{2}$ = atmospheric pressure

The Bat Life: To monitor the pressure of helium in the canister, Batman had placed 2 sensors which sense pressure and temperature at points $P_{1} a n d P_{2}$ . When the piston was in motion, Batman's suit registered an error in the canister. When he analysed the error back in the Batcave he noticed that the pressure at points $P_{1} a n d P_{2}$ were different. Which amongst the following statements is true?
