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?

• Chemistry -

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?

• Chemistry -

yes

• Chemistry -

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 />
