Why a room can be warmed by leaving open the door of an oven but cannot be cooled by leaving open the door of a kitchen refrigerator?

the second law of thermodynamics proves that heat always flows from hot to cold. It is hard to give good every day examples, since when you open the refrigerator door you feel cold but actually the room is warming the fridge.

Can a room be cooled by leaving the door of refrigerator open?
No, leaving the door of a refrigerator open will not cool a room, but will actually make the room hotter. A refrigerator cools its own interior by pumping heat to the heat exchange coils in the back (some models do not have exposed heat exchange coils, but the sides or back of the refrigerator have coils just underneath them, and they get hot). Those heat exchange coils pump heat into the room. Since the process is not 100% efficient, the amount of heat produced includes a certain amount of waste heat. As a result, pumping heat from one part of the room to another part of the room results in a net increase in heat.
A refrigerator does not cool the food inside it properly if the food is too tightly packed?
Food is cooled from surrounding air particles and so if a packet is obstructing the vibration of the particles the food will be unable to cool.
A refrigerator and air conditioner both remove heat from a cold reservoir and into a hot reservoir Why then does an air conditioner cool a room while a refrigerator warms a room?
Both an A/C unit and a fridge pump heat from one area into another. In the A/C unit the heat is pumped out of the room and into a discharge area, normally the outside atmosphere, thus the room is cooled, wheras for a fridge the heat is pumped from inside the fridge out into the room, thus the inside of the fridge is cooled and the room is warmed. The only difference between the working of the two is that the "room" is a different side of the heat pump.
What happens with water vapor when its cooled?
when water vapour is cooled it condenses and falls as rain
Can a kitchen be cooled by leaving the door of the refrigerator open?
No, although the short-term effect would be for the refrigerator air / freezer air to mix with and cool the air in the room.The function of refrigerator is a heat exchanger; it removes heat from the inside of the fridge and pumps it to the outside of the fridge.If we open the refrigerator door, it will remove the heat from the air that mixes inside, but then will exchange the heat back into the kitchen. That's why the room can't be cooled for a long period. In fact, due to waste heat, the room could become warmer once the refrigerator contents have reached room temperature.

How is the air cooled in a household refrigerator?
It goes through the pipes

Can it is possible to use water cooled condensor for domestic refrigerator?
Did you get an answer? I've found some references to water cooled refrigerators on boats, but can't find anything online about residential models.
I heard that hot chicken broth will spoil if put into a refrigerator in a sealed container. Should be cooled in the refrigerator first before putting on a lid tightly so that it won't spoil?
Bad advice.
Refrigerator not getting cold?
There is insulation between the freezer and refrigerator; additionally, in most refrigerators, the freezer is the only part that is mechanically cooled. The leftover cool air from the freezer is vented into the refrigerator section, and the dials that control the refrigerator's cooling levels generally just determine how much of the freezer air is allowed into the refrigerator chamber.
Is it safe to store food in a pot in the refrigerator?
Of course you can. The food in the pot will not cause any harm to your refrigerator as long as the pot has cooled down. It's probably not safe to put the Teflon pot in the refrigerator if it scorching hot. That might not be safe. Mr. Know it all
