Melalui proses evaporasi dan kondensasi, lemari es menghisap energi panas dari dalam dan mengeluarkannya ke dapur.

Freezers use a evaporation and condensation to pump heat out of the fridge and into the kitchen.
Even fridge magnets have magnetic fields approximately 200 times stronger than Earth’s.
The energy needed to pull magnets apart comes from you, and you get it from the food you eat. And the plants or animals you eat get their energy from other plants and animals, or from the Sun. All energy comes from somewhere.
