A rigid tank with a total volume of 0.05m^3 contains a movable piston separating the vessel into two compartments, each containing 25g of water. Initially, both compartments are at the same temperature. with A at a pressure of 10 kPa and a volume of 0.04375m^3. the weight of the piston applies a pressure of 50 kPa on the water in B. The water in B is then heated until it becomes a saturated vapor at a pressure of 200kPa, while the water in A is cooled to maintain its initial temperature. Find the change in temperature of the water in B and its final volume. please show all work.
