A) remain at same temperature
B) get heated
C) get cooled
D) first [b] and then [c]
Correct Answer: B
Solution :
In any refrigerator a certain amount of heat is absorbed from the objects you want to cool and a larger amount of heat is released to the outside through the radiator behind the refrigerator. When the door of a refrigerator is kept open, the compressor-will work all the time as the heat in the room is too large and temperature never reaches the cut off point of the thermostatic switch. So, more heat is released into the room, than is absorbed. If the ventillation is insufficient this will cause the room to warm up. If all the doors and windows in the room are closed and there is no ventillation, the temperature of the room will increase. Note: In a closed room temperature of room will increase even when the door of the refrigerator is kept closed. This is because the radiator of the refrigerator releases heat into the room.
