This is similar to a question I've asked in a couple of forums, and never got an answer.

Is the heat exchange greater if I leave the refrigerator door open while making a sandwich, or if I keep wafting the circulation by opening and closing the door several times to take things out and put them back? In other words, was my mother right or wrong when she yelled "close the fridge, you're wasting electricity".
