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.


What would you expect to happen to a balloon filled with air if it was out into a refrigerator?

The balloon would shrink in size as the air inside cools and contracts. This is because gases, like the air in the balloon, contract when they are cooled and expand when they are warmed.


Cooled liquid leaving the radiator travels through the?

coolant hose back to the engine to continue the cooling cycle. The coolant absorbs heat from the engine and then releases it to the radiator where it is cooled down before returning to the engine. This cycle helps regulate the engine temperature and prevent overheating.


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.


Is cooled a verb?

Yes the word cooled is a verb. It is also an adjective to describe something at a lower temperature.

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.

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.


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


Which food was correctly cooled?

The soup was correctly cooled by being transferred to a shallow container and placed in an ice water bath before being stored in the refrigerator to ensure rapid cooling and prevent bacterial growth.


Why does a refrigerator warm a room?

If you feel behind a fridge, you will feel the warm air. This warmth is from the inside of the fridge as the inside is cooled, and from the pump.
