Various effects of heat on the freezing of water were described by ancient scientists, including Aristotle: "The fact that the water has previously been warmed contributes to its freezing quickly: for so it cools sooner. Hence many people, when they want to cool water quickly, begin by putting it in the sun."
"Frost-Free" refrigerator/freezer units usually use a heating element to defrost their evaporators, a pan to collect and evaporate water from the frost that melts from the cold plate and/or evaporator coil, a timer which turns off the compressor and turns on the defrost element usually from once to 4 times a day for periods usually ranging from ...
Supercooling is the cooling of a liquid below its freezing point without it becoming solid. Freezing point depression is when a solution can be cooled below the freezing point of the corresponding pure liquid due to the presence of the solute; an example of this is the freezing point depression that occurs when salt is added to pure water.
Cooked Pasta. Probably worse than overcooking pasta and letting it bloat with extra water is freezing it. Once you take it out of the freezer, it turns into a squishy puddle formerly known as noodles.
Grated Cheese. Throwing a bag of grated cheese in the freezer just feels … wrong. But multiple Redditors say that shredded cheese fares better than blocks or slices.
Ice crystals in a frozen pond. When the water cools slowly, crystals are formed. When water freezes slowly, crystals grow from fewer nucleation sites, resulting in fewer and larger crystals. This damages cell walls and causes cell dehydration. When water freezes quickly, as in flash freezing, there are more nucleation sites, and more, smaller ...
It takes between a few hours to a few days for water in a rain barrel to freeze solid in cold weather. This depends on how full the barrel is, the temperature, and other factors. Read the original ...
One example of deposition is the process by which, in sub-freezing air, water vapour changes directly to ice without first becoming a liquid. This is how frost and hoar frost form on the ground or other surfaces. Another example is when frost forms on a leaf. For deposition to occur, thermal energy must be removed from a gas.
