Question: Unit mass of a liquid with volume ${{V}_{1}}$ is completely changed into a gas of volume ${{V}_{2}}$ at a constant external pressure $P$ and temperature $T$. If the latent heat of evaporation for the given mass is L, then the increase in the internal energy of the system is


1) Zero
2) $P({{V}_{2}}-{{V}_{1}})$
3) $L-P({{V}_{2}}-{{V}_{1}})$
4) $L$
