Unit mass of a liquid with volume $\mathbf{V}_{1}$ 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
Text Solution
Verified by ExpertsThe correct answer is:
C
$\Delta Q = \Delta V + P \Delta V$ ⇒ ⇒ mL = Δ Δ U + P (V 2 – V 1 )
⇒ ⇒ Δ Δ U = L – P (V 2 – V 1 ) ( : m = 1)
