Refrigeration - Part 2: Heat transfer Heat transfer is an interesting part of science. Your refrigerator uses electricity to displace the heat inside the fridge to the exterior of the fridge, and keeps these environments isolated through the use of insulation and seals. As soon as any contents (say, a margarine tub) from inside the fridge are moved to outside the fridge (the counter, the table) you have begun to let the heat in the room transfer into those contents.
