A pressure cooker containing some water with an internal energy of 300 kJ is heated by a gas burner. 0.5 kg of steam with an enthalpy of 1800 kJ/kg escapes through the safety valve. The heat loss through the wall of the cooker is 250 kJ. If the final internal energy of the water and steam in the cooker is 500 BTU. Find the heat supplied to the cooker.
