371337 \(1\;g\) of a liquid is converted to vapour at \(3 \times {10^5}\;Pa\) pressure. If \(10 \%\) of the heat supplied is used for increasing the volume by \(1600\;c{m^3}\) during this phase change, then the increase in internal energy in the process will be

371338 Assertion :
If an electric fan be switched on in a closed room, the air of the room will be hot.
Reason :
There will be evaporation of sweat by a human there.

371339 A barometer tube has length \(90\;cm.\) It contains some air above mercury. On some hot days when temperature is \(50^\circ C\) and true atmospheric pressure is \(75\;cm\) of \(Hg,\) the reading of the mercury level is \(74.8\;cm.\) If the reading is observed to be \(75.1\;cm\) on some another day when temperature is \(25^\circ C,\) then Find the true pressure on that day will be

371340 Assertion :
Perfectly reversible systems are difficult to find in real world.
Reason :
Most processes are dissipative in nature.
