1.	1 cm of water at 100°C and 1 atm pressure is heated to convert it to 1521 cm3 vapour. Findincrease in internal energy if latent heat ofvaporization of water = 540 cal/g.(1) 3.26 kJ(2) 2.12 kJ(3) 4.18 kJ(4) 1.05 kJ
Answer» ter at 100°C and 1 atm pressure is heated to convert it to 1521 of vapour. The heat of vaporization of water =540 cal/g. Find the INCREASE in INTERNAL energy.Work done, W = Pressure * Change in Volume = Heat required, Q = Mass * Latent Heat of vaporisation = Increase in internal energy, ΔU = Q - W = 2103.3 J = 2.103 kJHence option (2) is CORRECT.
