wiki Word:Freezing Point

Definition:Freezing Point is the temputure at which a liquid becomes a solid at normal atmosperic pressure.  More specificly, Freezing Point is the temputure at which solid and liquid phases coexist in equalibrium.  The normal freezing point is the temputure that a substance freezes at at one atmospheric pressure.

The freezing point is an important material property to know.  Some materials must be prevented from freezing to protect their integrity or the products packaging.  The freezing point of different substances vary greatly.  Mercury for example freezes at -38.87 C.  However Gold has a freezing point of 1063 C.  The freezing point of any substance depends on the pressure pushing against the substance.  Freezing points are based on a pressure of one atmosphere (14,696 pounds per square inch), the pressure of the atmosphere at average sealevel.

Frozen Water A.K.A. Ice Cube / Water freezes at 32 degrees Fahrenheit and 0 degrees Celsius.

Freezing points of different materials are important in knowing when a certain element freezes: in Medical Field, Food Industry, Construction Industry and Science.
