1.	The door of a running refrigerator inside a room is left open. The correct statement out of the following ones isA. The room will be cooled slightltB. The room will be warmed up graduallyC. The room will be cooled to the temperature inside the refrigeratorD. The temperature of the room will remain uneffected.
Answer» Correct Answer - B Cofficient of performance of refrigerator is `(Q_(2))/W= (T_(2))/(T_(1)-T_(2))` When the door of a running refrigerator inside a room is left open, `T_(2)rarrT_(1)`. Coefficient of performance increases. `Q_(2)` increases. Therefore, heat energy given to the room increases. Hence the room will be warmed up gradually.
