In a steam boiler, hot gases from a fire transfer heat to water which vapourizes at constant temperature.In certain case, the gases are cooled from 1100°C to 550°C while the water evaporates at 220°C. Thespecific heat of gases is 1.005 kJ/kg K, and the latent heat of water at 220°C is 1858.5 kJ/kg. All the heattransferred from the gases goes to the water. How much does the total entropy of the combined system ofgas and water increase as a result of irreversible heat transfer ? Obtain the result on the basis of 1 kg ofwater evaporated. If the temperature of the surroundings is 30°C find the increase in unavailable energydue to irreversible heat transfer.

A rigid vessel of volume 0.2m³ contains 10 kg of (liquid + vapor) water at 200°C. What are the pressure and internal energy of the water?
A closed container with constant volume insulated against heat is divided into two compartments by a steel curtain. Compartment A contains 2 kg of water at 800 kPa pressure and 80 oC temperature. The other compartment is empty (vacuum). Then the steel curtain is removed and the water fills the whole container. Finally, calculate the final temperature of the water and the volume of the tank, since the pressure of the water in equilibrium is 10 kPa.
