Here are two facts that you must know before any of the rest of this makes sense (as if that would help): 1) It is really cold here in NJ today. Below freezing. 2) We have a refrigerator in our garage.
So I go to the kitchen to get a refreshing Diet Coke. And there are none. So I go out to the garage to get my soda and it strikes me that it's really cold out today. I open the refrigerator, get my soda and start to walk back into the house when the strangest thought occurs to me. Is my refigerator actually keeping my soda warm? I mean, if the temperature in the garage gets below the 40 - 45 degrees (F) that the refrigerator is set at, does it become the job of the refrigerator to keep my soda warm? And how does it do that exactly?
It's like that old joke about the good old reliable Thermos ©. "It keeps things hot, it keeps things cold. How does it know?"
