In a highly evacuated flask an ampoule containing 2.4 grams of water is introduced, the temperature of the system being 30 C. On breaking the ampoule 0.80 grams of water evaporates in the equilibrium state. The heat of vaporization of water is 590 cal/gram Calculate L, Q, H, S and G. Answer L- 0, Q=472 cal, H=498.7 cal, S= 1.646 e.u. and G=0.
