Does a refrigerator give off hot or warm air into the room? Or do anything that would affect the temperature of the room it's in?
The from inside the refrigerator must go somewhere. A small refrigerator, designed for use in homes, moves the heat from inside the refrigerated space to outside and into the room. Large commercial refrigerators may have the heat exchanger placed outside (similar to air conditioning units) where the hot air is exhausted.
So a refrigerator in your kitchen would heat it up?
yes
it may not be the best word. A refrigerator in the kitchen would warm the kitchen if the refrigerator is cooled to a temperature lower than room temperture.
ok thanks :)
at room temperature (about 20degree C) milk turms sour in about 64 hours. In a refrigerator at 3 degree C, milk can be stored for about three times as long before turning sour. Determine the approximate activation energy for the reaction that causes milk to sour and how long it would take for milk to sour at 37 degree C<br />
A refrigerator typically gives off hot air into the room. This is because refrigerators work by removing heat from their interior compartments and expelling it to the surroundings. To better understand why this happens, let's dive into the science behind refrigeration.
Refrigerators operate using a process called the refrigeration cycle. It involves several key components, including a compressor, a condenser, and an evaporator. First, the compressor compresses a refrigerant gas, causing its temperature to rise. This high-pressure, high-temperature gas flows into the condenser coils located at the back or bottom of the fridge.
As the hot refrigerant gas travels through the condenser coils, it releases heat to the surrounding air. This heat transfer process cools down the refrigerant, condensing it into a high-pressure liquid. The release of heat is why the back or bottom of a refrigerator often feels warm.
The liquid refrigerant then moves into the evaporator coils inside the fridge, where it undergoes a phase change and turns back into a gas. During this phase change, heat is absorbed from the interior compartments of the refrigerator, lowering its temperature. Thus, the evaporator coils actively cool down the fridge's contents.
Finally, the refrigerant gas is taken back to the compressor to restart the cycle. This continuous process of heat absorption at the evaporator and heat dissipation at the condenser is what allows the refrigerator to maintain a colder temperature inside while releasing heat outside.
In summary, a refrigerator removes heat from its interior compartments and expels it to the room through the condenser coils, which results in the release of hot air. Therefore, the overall effect of a refrigerator on the room's temperature is warming it up slightly.
