freezing point

noun

1. the temperature below which a liquid turns into a solid. It is equal to the melting point

freezing point

/ frē′zĭng /

1. The temperature at which a liquid, releasing sufficient heat, becomes a solid. For a given substance, the freezing point of its liquid form is the same as the melting point of its solid form, and depends on such factors as the purity of the substance and the surrounding pressure. The freezing point of water at a pressure of one atmosphere is 0°C (32°F); that of liquid nitrogen is −209.89°C (−345.8°F).

freezing point

1. The temperature at which a liquid changes into a solid ; the same temperature as the melting point . ( See phases of matter .)

Notes

Water freezes at thirty-two degrees Fahrenheit (see also Fahrenheit ) or zero degrees Celsius .

From Science Daily

Sugar has the physical function in slushies of decreasing the freezing point of water.

From Salon

They also used heavy water, a form of water where the hydrogen atoms are replaced by deuterium, which gives the water a higher freezing point, and helps create the smooth structure.

From Science Daily

A dash of greenhouse effect is useful -- without it, Earth would have an average temperature below the freezing point of water, looking like a ball covered with ice and hostile to life.

From Science Daily

As ice crystals start to form, the concentration of sugars and other dissolved materials in the unfrozen liquid increases, which further lowers its freezing point.
