Common question In the figure shown, the system is a pure substance kept in a piston-cylinder arrangement. The system is initially a two-phase mixture containing 1 kg of liquid and 0.03 k of vapour at a pressure of 100 kPa. Initially, the pistion rests on a set of stops, a shown in the figure. A pressure of 200 kPa is required to exactly balance the weight of the piston and the outside atmospheric pressure. Heat transfer takes place into the system until its volume increases by 50%. Heat transfer to the sytem occurs in such a manner that the pistion, when allowed to move, does so in a very slow (quasi-static/quasi-equilibrium) process. The thermal reservior from which heat is transferred to the sytem has a temperature of 400oC. Average temperature of the system boundary can be taken as 175oC. The heat transfer to the system is 1kJ, during which its entropy increases by 10J/K. Specific volumes of liquid vt and vapour vg phases, as well as values of saturation temperatures, are given in the table below.
