Please, solve this problem in full details and calculations:

Two tanks of the same volume are connected by a pipe containing a valve. Initialey the valve is closed, one tank is evacuated, and the other tank contains 30g of saturated water vapor at 10 bars. The valve is opened and the steam flows into the evacuated tank until pressure equilibrium prevails. If the steam temperature at the end of the process is 200C, determine (a) the final pressure, in bars, (b) the heat transfer, in kilojoules, and (c) the total entropy change, in kJ/K, if the heat is supplied from a reservoir at 200C
