container has a volume of  1 m3 and holds air at 344.8 kPa and 273 K. Heat is added until the temperature is 600 degrees K. (Rair = 0.287 kJ/kg K), (kair = 1.4). (a.) What is the mass of air? (b.) What is the final pressure?, (c.) What is the change in enthalpy? and

Mr Zul operates a hot plate. He places a closed, rigid container of volume 0.5 m3on the hot plate. Initially, the container holds a saturated mixture with quality ofvapour of 0.5, at a pressure of 100 kPa. After heating, the pressure in the containerincreases to 150 kPa.a) Calculate the mass of vapour at the initial and final states (in kg).b) If heating is allowed to continue, find the pressure (in kPa) when thecontainer holds only saturated vapour.c) Sketch the T – v diagram for this system.
