Temperature vs time plots, showing the Mpemba Effect. The Mpemba effect is the name given to the observation that a liquid (typically water) that is initially hot can freeze faster than the same liquid which begins cold, under otherwise similar conditions.
Freezing is a common method of food preservation that slows both food decay and the growth of micro-organisms. Besides the effect of lower temperatures on reaction rates, freezing makes water less available for bacteria growth. Freezing is a widely used method of food preservation. Freezing generally preserves flavours, smell and nutritional ...
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 ...
The freezing from the surface or from within may be random. [11] However, in the strange world of water, tiny amounts of liquid water are theoretically still present, even as temperatures go below −48 °C (−54 °F) and almost all the water has turned solid, either into crystalline ice or amorphous water.

When water freezes, it increases in volume (about 9% for fresh water). [8] The effect of expansion during freezing can be dramatic, and ice expansion is a basic cause of freeze-thaw weathering of rock in nature and damage to building foundations and roadways from frost heaving. It is also a common cause of the flooding of houses when water ...
Residents should contact property managers, landlords or maintenance personnel to locate the property owner’s water cut-off valve and find ways to avoid pipe breakage during a freeze. What to do ...
A water temperature of 10 °C (50 °F) can lead to death in as little as one hour, and water temperatures near freezing can cause death in as little as 15 minutes. [37] During the sinking of the Titanic, most people who entered the −2 °C (28 °F) water died in 15–30 minutes. [38]
