I need the answer as soon as possible A rigid tank is partitioned in two regions. Region A initially contains 10 kg of H20 solid (ice) at-20 °C. Region B initially contains 0.50 kg ofH20 saturated vapor at 200 °C. A door between the two region opens allowing the masses to mix. Heat transfer with the surrounding allowsthe final temperature to reach 90 °C at equilibrium. KE and PE are negligible. The final pressure inside the tank =,(bar)

Given:Region A: mass of solid ice, ma=10 kgTemperature, Ta=-20o CRegion B:mass of saturated vapor,…
