Question

which process is mainly responsible for the heat from the kitchen entering the refrigerator each time the door is opened

Answer 1

hey mate;

here is your answer....

It takes air inside the fridge and cools it by removing heat from it. This heat has to go somewhere, though, and is usually blown out the back of the fridge by a little fan. (If you feel the back of a fridge on the outside it will usually be warm if the unit is running). A fridge can be though of as a "heat pump".
