A closed rigid tank with volume 3.2 m3 contains 182 kg of steam at pressure 40 bar. The tank is equipped with an alarm that will sound if pressure exceeds 80 bar. The tank is heated until the alarm sounds. Determine the state of state steam at that point. If the state is vapor/liquid mixture, report the mass fraction of the vapor.\
