(25 pts) A well-insulated and well-sealed 2-m x 3-m x 4-m room is initially at Tal = 22 °C and p = 100 kPa. A mass of mw = 20 kg of liquid water at Tw./ = 80 °C is brought into the room and the system is allowed to reach equilibrium conditions (state 2). 2m x 3m x 4m ROOM 22°C 100 kPa Specific heat values for the air and water may be taken as Cp,air = 1.005 kJ/kg-K;...
