A steel tank with total internal volume of 250 L was initially filled with a saturated mixture of water and steam at 120o C and quality of 60%. Heat is slowly transferred to the tank contents, vaporizing all the contents and turning it to saturated steam still at 120o C. A safety valve allows excess saturated steam to be released to maintain the final state. How much heat is transferred (amount and direction) in the process and how much steam was released?
