Steam is contained in a closed rigid container. Initially, the pressure and the temperature are 1.4 MPa and 250°C, respectively. The temperature drops as a result of heat transfer to the surroundings. Determine the pressure at which condensation first occurs, in MPa, the fraction of total mass that has condensate when the temperature reaches 100 °C nd the heat released during the process. What percentage of the volume is occupied by the saturated liquid at the final state.
