Ovens make sense. We take electrical energy, convert it to thermal energy, them transfer that thermal energy into the object we are trying to heat.
Refrigerators baffle me. Somehow it costs energy to remove energy from something else. Basically, we convert electrical energy into NEGATIVE thermal energy. How does that happen, and where does the extra energy go?
