A rigid vessel contains 1 kg of a mixture of saturated water and saturated steam at a pressure of 140 x 10* N/m2. When the mixture is heated the state passes through the critical point. Evaluate: (a) the volume of the vessel; (b) the mass of liquid and of vapour in the vessel initially; (c) the temperature of the contents of the vessel when the pressure has risen to 30 x 10° N/m2; (d) the heat transfer required to produce the final state (c).
