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.\

Ametal ring 4.20 cm in diameter is placed between the north and south poles of large magnets with the plane of its area perpendicular to the magnetic field. these magnets produce an initial uniform field of 1.12 t between them but are gradually pulled apart, causing this field to remain uniform but decrease steadily at 0.240 t/s . (a) what is the magnitude of the electric field induced in the ring? (b) in which direction (clockwise or counterclockwise) does the current flow as viewed by someone on the south pole of the magnet?
