The design of the household fridge is based around two things that you will have experienced.
1. If you wet your skin then after a short time your skin will feel cold. This is because when a liquid evaporates it absorbs heat from its surroundings.
2. When you pump up the tire on a bicycle the pump's body gets hot. This is because when a gas is compressed it gets hotter.
The fridge contains a liquid which evaporates very easily at around the freezing point of water. This passes through a heat exchanger inside the fridge (usually in the ice making compartment) where it evaporates, sucking heat out from the fridge. The cold gas circulates to another heat exchanger located outside the fridge. There it is compressed. This turns it back into liquid, and also produces heat, which the exchanger transfers to the outside world.
Answer 2.
In the kitchen of nearly every home in America there is a refrigerator. Every 15 minÂutes or so you hear the motor turn on, and it magically keeps things cold. Without refrigeration, we'd be throwing out our leftovers instead of saving them for another meal.
The refrigerator is one of those miracles of modern living that totally changes life. Prior to refrigeration, the only way to preserve meat was to salt it, and iced beverages in the summer were a real luxury.Related Topics
The basic idea behind a refrigerator is very simple: It uses the evaporation of a liquid to absorb heat. In this article, you'll find out how your refrigerator performs its magic based on this simple principle. We'll also look at cold packs, electronic coolers and the propane refrigerators found in
what may be causing my freezer to work but my refrigerator not to work
It depends on what kind of refrigerator you own.
the refrigreator wont work
Normally, heat moves from a higher temperature to a lower temperature. Devices that use work to move heat are called heat movers. A refrigerator is an example of a heat mover because it takes the heat from inside of the refrigerator and moves it to the outside. The 2nd law of thermodynamics allows this to occur if work is done in the process. A refrigerator does work as it moves the heat from inside the refrigerator to the warmer room.
thank you
i dont no

This gas in your refrigerator draws heat away and makes the objects cold
Gnats can live in refrigerators that do not work. However, they can't live inside a cold working refrigerator.
it makes thing hot and it does not work why do u not have one poor person
because it needs air to work
