A small capsule having a volume of 5 cm' contains liquid water at 7.5 MPa and 60"c. The capsule is located inside an evacuated container having a volume of 0.025 m'. Subsequently, the capsule is broken by some appropriate mechanism so that the water is able to evaporate and fill the large container. Calculate the final density of the water/vapour mixture, assuming that water/vapour mixture can the exchange heat with the surroundings through the walls of container. Determine the heat exchange with the surroundings.
