it compresses air in the pipe's behind the fridge and places it into chamber, to keep it cold it takes air from within the fridge and re-compresses it.A refrigerator will keep food cold by converting gas into liquid, then liquid into vapour. Basic physics maintains that when two surfaces come in contact with the other, the surface with the higher temperature will cool to equal the temperature of its alternate. Coils and metal parts inside a refrigerator are loaded with cold liquid. The liquid inside generates cold air outside the coils. This happens when the heat from inside the refrigerator reduces its temperature to "match" temperatures with the cold liquid inside the coils. When you open a refrigerator door, you generally will notice a dramatic change in air temperature. Food inside is kept cold because the refrigerator is able to convert gas into liquid. That liquid passes through a series of parts that can also opt to change that liquid into vapour--this is done by compressing molecules.
Food doesn't exactly stay fresh in the refrigerator. Ripening, spoilage and degradation are delayed due to the lower temperature. At some point, the food will no longer be 'fresh' even though it is stored in the refrigerator.
By keeping down the temperature of food you keep the bacteria that decomposes your food at bay. They thrive in warm moist climate, where a cold moist climate is colder and not as friendly to live in. Freezing is another example of keeping food below the temperature for the bacteria to flourish.
By using cold air. Bacteria and molds, which spoil food, are most active in warm temperatures. In refrigerated air they can still work, but they are greatly slowed down - to where it takes days for them to spoil the food that is refrigerated.
By keeping food cold - this greatly slows down the growth of molds, enzymes and bacteria.
Many foods last longer at cooler temperatures. Refrigerators provide this cooler temperature.
It stops the bacteria growing.
You are more likely to find mold or mildew growing in your refrigerator. It could be caused by rotting food stains or rotting water.
in ancient time the people use ice and snow to preserve the food. Then they think about a machine to cool the food . this leads to the invention of refrigerator.
to keep food cold?
To keep food from spoiling and keep it cold.
Because it keeps food cold.
You need the refrigerator so you can keep food fresh for longer periods of time. You can keep almost anything in it.
To keep food fresh
To keep it fresh for longer.
This food will keep for about 3 days in the refrigerator. Place the food in an air tight container for the best results. This food can easily be transferred to the freezer for longer storage time.
depends on the model of it. a refrigerator needs to keep food at 42 degrees or lower to keep the food same, if your drink chiller can maintain that temp then yes, if not, no
The Germans used to trap jews in until they froze and that is where they got the idea of ice in a drink
This food will keep for about 5 days in the refrigerator. Place the food in an air tight container for the best results. This food can easily be transferred to the freezer for longer storage time.
