class 11 Physics Thermodynamics
yes it is because when we open the door of refrigerator our system becomes refrigerator+room. since the door is open the heat took out from the system(room+refrigerator).so the temperature got decreases,but we also add some more heat to the refrigerator in the form of electrical energy. And finally reject all this heat back to the room.
So;we actually raise the heat content in room at the rate of dissipation of compression work:thus the temperature of room increases.
