A piston-cylinder device contains satuated water vapor with a constant pressure. The mass and the pressure are listed in the table below. The water is heated by a resistance heater (see the picture below) within the cylinder. The heat supplied by the heater is given in the table below. The cylinder is insulated so there is not heat loss. (a) Determine the enthalpy per unit mass after the water vapor received heat. (b) Determine the temparature after the water vaopr received heat. Parameter Pressure Mass of water Heat supplied by the heater Unit kPa g KJ Value 300 26 7.1 heater
