FREEZING POINT/FREEZE The process of changing a liquid to a solid. The temperature at which a liquid solidifies under any given set of conditions. Pure water under atmospheric pressure freezes at 0°C or 32°F. It is the opposite of fusion.
FREEZING POINT: Temperature of solidification of a liquid under given conditions.
HEADWIND: A wind blowing in a direction opposite to the course of a moving object. Often used when referring to winds affecting ballistics.
freezing point: the temperature at which a substance changes from a liquid to a solid. For water, it is 0°C or 32°F.
front: boundary where two air masses with different temperatures and moisture content meet.
Freezing Point
The temperature at which a liquid solidifies under the influence of a particular set of conditions.
True freezing point The temperature at which the liquid and solid forms of a substance may exist in equilibrium at a given pressure (usually one standard atmosphere). The true freezing point of water is known as the ice point.
CelsiusA temperature scale in which zero is the freezing point of water and one hundred is the boiling point.
CELSIUS TEMPERATURE SCALE A temperature scale where water at sea level has a freezing point of 0 degrees C (Celsius) and a boiling point of +100 degrees C. More commonly used in areas that observe the metric system of measurement.
SupercoolTo cool a liquid below its freezing point without solidification or crystallization.
On this scale, the freezing point of water is 32°F and the boiling point is 212°F.
The freezing point of water is +273ºK (Kelvin) and the boiling point of +373ºK. It is used primarily for scientific purposes. It is also known as the Absolute Temperature Scale.
supercooling"(Also called subcooling or undercooling; see note below.) The reduction of temperature of any liquid below the melting point of that substance's solid phase; that is, cooling beyond its nominal freezing point.
Contrast with freezing point.MeniscusIn hydrologic terms, the curved surface of the liquid at the open end of a capillary columnMercury BarometerAn instrument for measuring atmospheric pressure.
Within this layer, temperature increases as altitude increases (see temperature inversion); the top of the stratosphere has a temperature of about 270 K (âˆ'3°C or 26.6°F), just slightly below the freezing point of water.
Although we commonly speak of 0oC as the freezing point of water, water, especially in the droplet form, rarely freezes at this temperature.
A temperature scale where water at sea level has a freezing point of 0°C (Celsius) and a boiling point of +100°C. More commonly used in areas that observe the metric system of measurement. Created by Anders Celsius in 1742.
Celsius Scale - temperature scale on which the interval between the freezing point and the boiling point of water is divided into 100 degrees, with 0 degrees representing the freezing point and 100 degrees the boiling point ...
Like condensation, the freezing of water involves the process of nucleation. See ice point, freezing point, true freezing point, melting point. 2. Said of an environment when its temperature is equal to or less than 0°C (32°F). See freeze.
The temperature scale where 32°F is the freezing point of water and 212°F is the boiling point (at sea level).
Fahrenheit temperature scale ...
Supercooled - any liquid which remains liquid below its normal freezing point.
Synoptic scale - the size of features which take a day or more to pass. They are usually a thousand miles or so across.
ABSOLUTE TEMPERATURE SCALE A temperature scale with a freezing point of +273°K (Kelvin) and a boiling point of +373°K. Related term: Kelvin Temperature Scale ...
A liquid-in-glass thermometer containing an alcohol liquid, such as ethanol. Because alcohol has a low freezing point, ...
The standard scale used to measure temperature in most areas outside the United States. On this scale, the freezing point of water is 0?Ǭ?F and the boiling point is 100?Ǭ?F.
Celsius temperature scale: A temperature scale where the freezing point of water occurs at 0 ?C and the boiling point at 100?C, at sea level.
An accumulation of supercooled water droplets on a vessel or object which are below the freezing point of water. It usually develops in areas with winds of at least 25 knots. The following table gives the Categories of Freezing Spray/Icing.
Kelvin (K) scale - A temperature scale where 0º K represents absolute zero, the freezing point of water is 273º K, and the boiling point of water is 373º K.
Freezing Spray: An accumulation of supercooled water droplets on a vessel or object which are below the freezing point of water. It usually develops in areas with winds of at least 25 knots.
frost: water that has condensed at a temperature below the freezing point, thus has turned to

2. What does salt do to the temperature of ice in the can?
Adding salt to ice cools the temperature to below freezing point (0°C). Now, rather than dew forming, crystals of ice, known as frost, form.
Fahrenheit - the standard scale used to measure temperature in the United States; in which the freezing point of water is thirty-two degrees and the boiling point is two hundred and twelve degrees.
Frost: Deposit of ice on the surface when the air temperature gets in contact with it below the water freezing point (0ºC).
SUPERCOOLED - Term used to describe water (or any liquid) that is still in liquid phase even though it is below the freezing point (solidification temperature) of that liquid.
