The first fridges used ammonia and an electrical pump which would forced the liquid through tubes that ran along the back of the refrigerator. With time the moving parts involved in the electrical pumps would cause breaks in the tubes or the pump itself and the ammonia would leak into the home, often causing death to the family. In the 1920's Einstein, for this very reason invented the very first pump with no moving parts also known as the electromagnetic pump. This was then used to pump the ammonia until Freon gas (Chloro-Fluoro-Carbon). As it is more efficient and safer.
The actual cooling of the food is related to the second law of thermodynamics. As long as the tubes filled with ammonia are cooler than the food within the fridge, the heat will constantly move from the food to the cold tubes until it reaches a temperature equilibrium.

Why you are keeping things in the fridge?
people keep things in the to keep things cool
Where do you keep your food?
I keep my food inside my buttocks. Except a lot of times, when I take out my potato chips, they are covered in feces but your feces cool the food down like a fridge. I highly recommend storing your food this way as you can keep it cool while you walk. Sometimes you run out of feces so when I do, I always pray to the fecal fairy that night and overnight she refilled my fecal glands so I could keep my food cool again.
Why does food go off more slowly in a freezer than in a fridge?
because it does and food will go off even longer if you keep it in your bum because the poo keeps it nice and cool.
How is fridge harmful to environment?
To keep the food in the refrigerator cool, there is a thermally-insulated layer to keep the heat out as well as an in-built heat pump (chemical or mechanical) to transfer the heat from within the fridge to it's external environment, increasing the temperature of the surrounding air.

Is it ok to leave the refrigerator open?
No, for two reasons. First, the fridge door has to be closed to keep the air temperature inside the fridge cool enough to keep the foods cold and safe. Second, leaving the fridge door open causes the refrigerator to run more, costing more energy and running up the electric or gas bill.
