if we put a refrigerator on a closed insulated room we operate the refrigerator and open its door then the room temperature decreased- increased or remain constant why?
Opening a refrigerator door in a closed insulated room does not modify the room temperature which remain constant
The room temperature does not effect bt the refrigirator self
There will be no noticable change in room temperature.. Refrigerator do not operate to condition the room air but its just releasing little amount of cold air from it . If the insulated room temp is higher than the refrigerator, the energy travels from refrigerator to the room and the energy gradience becomes constant very quck at the minute amount of cold air travel(no noticalble eff to room temp). If the room temp is lower than the refrigerator temp then the energy travels to the refrigerator and since the system is very smaller than surroundings the change(decrease) in refrigerator temp can be noticable. However, the change in room temp can be neglected if its a large room.
