2,3) In a plunger cylinder device, 15 kg of air is heated from 25°C to 77°C by passing curr through a resistance heater inside the cylinder. The initial pressure in the cylinder is 300 1 and in the process 60 kJ of heat is lost to the environment. Determine the electrical ene supplied during the process and express it in units of 1-Wh
