well, id have to catch my refrigerator to find out. since its running.

The question is phrased too vaguely. Is the room closed and thermally insulated or not? Is the refrigerator powered by a mains outlet or a battery? Are we talking about the temperature of the whole room or the temperature of the air in it? And after how much time?

if the fridge is in a closed system e.g. a room, cold air escape into the room however the fridge now works harder to cool the air inside the fridge, since a fridge works by transferring the heat from inside to the outside and no fridge is 100% efficient, the extra heat generated and released into the room is higher than amount of heat absorbed by by the cold air

I mean, the second you open it the room gets colder. But then as you run it the room will gradually start warming even past the initial temperature. Unless of course the back of your refrigerator is in front of an AC intake vent for you homes HVAC in which case the room will get colder and stay colder.

I would say it depends because the heat from the fridge was already in the room, while the new cold air would cool it down. So if you measure the temperature next to the door soon after it was opened, that area becomes colder, even if the temperature will slowly rise and become hotter.

but... But Spongebob taught me that not only the room but the whole house gets colder

I don’t think this is correct. But I could be wrong. So yes, the fridge is on, causing heat. And yes, it’ll have to run more after you let the cold air out which will also cause heat. But that’s the point. When you open the door, you “let the cold air out” meaning the room gets colder. At least for the moment you open the door (not ultimately). There’s no way that the act of opening a door with cold air in it would somehow make the area the cold air escapes to hotter.

Just finished reading What if? 2 by randall munro and this was literally one of the questions!

Fridge cools by thermal transfer, so the only net heat exchange when the door is open is the power running the mechanism.

The refrigeration effect is the total heat rejected by the condensor. The heat is added into the system in two ways: one being the evaporator, and two being the compressor. The compressor component requires work to be done by adding energy. Even if the fridge was closed, it would still be adding heat to its surroundings, since it is a closed system and the evaporator expels the heat. But, yes it would get hotter because the refrigerator is basically now just expelling the heat of your house + the sensible heat added by the conpressor.

I wondered why the answer is wrong and then I realised that you need power to cool down the fridge. And some of the power will be transferred to heat. But instantly the room gets colder :D

Since the fridge is running and you’re chasing after it you and the fridge both start getting hotter bc physical exertion. This heats up the room.

This question is too vague. If we're talking about a closed insulated room, then just having a running refrigerator would make it warmer, and compared to that higher temperature opening the door would lower the temperature albeit temporarily. However, compared to the temperature the room would be without the fridge running or after a sufficient amount of time, it would still be hotter. I'm guessing the latter is what the question is asking, but the question is worded very poorly.

This will depend on the time frame of your experiment. In the short term the room will get colder, but in the long term the room will get hotter.

I'd say some of the cold air goes out coling the room for a bit but then it'd need to be re heated even more to cool the refrigerator

Imagine you have a refrigerator in your room that is running, and you open the refrigerator door. Without searching it up, what do you think happens to the temperature of the room?
