A rigid container contains 0.21 kg of hot saturated vapour at an unknown initial pressure P1. The container is cooled and the temperature drops to 98C. It is found that the contents of the container now (at 98C) are a mixture with quality 0.23. Calculate the amount of energy that was removed from the container, in KJ. Neglect kinetic and potential energy changes. Note that the reported heat transfer must be negative because energy is leaving the container
