An insulated rigid tank contains a saturated liquid-vapor mix of water initially at a pressure of 100 kPa. The
mass of the mixture is 5 kg, but only 75.6 % of the total mass is liquid. An electric resistance heater is turned
on within the tank until all the water has just vaporized. The heater power is a constant 2.2 kW. Hint: you will
not need to interpolate to find the solution to part (b).
