Pure water, at normal atmospheric pressure freezes at 0 deg C. If the pressure is greater than normal atmospheric pressure (760mm of Hg) or if the water contains dissolved substances, its freezing point will be below 0 deg C.
The freezing point of pure water, at normal atmospheric pressure is 0 degrees Celsius. Both the factors mentioned affect the freezing point of water. Solvents, such as common salt, lower the freezing point of water to something like -17 degrees C. Additional pressure will also lower the freezing point of water.
It would be ice
Every point on the Celsius/Centigrade scale is added to the number 273.15 and this is the reading of the thermometer calibrated for Kelvin. Remember, the Kelvin scale does NOT use the degree title or symbol, so 0 degrees Celsius/Centigrade is equal by definition to 273.15 Kelvin. 0 K is the lowest possible reading & is termed absolute zero. Kelvin is more useful in scientific calculations since it is designed using the standard units of volume, pressure, temperature and so on. It plugs into normal scientific units without having to make conversions.When I say degrees Celsius, this is very similar, but not exactly the same as degrees Centigrade. Celsius was calibrated by a physical phenomenon, the point at which water froze was considered 0 degrees Celsius and when water boils the 100 degree Celsius mark was made to produce the Celsius scale (actually originally the scale was backwards and the two numbers were simply switched, but that can be confusing!) Centigrade, was basically a set of evenly distributed marks to notate each degree (the order was correct at this point and the Celsius scale was flipped also to be the normal scale we know today. Since Centigrade was based off of Celsius, it was prone to the error of measuring a perfect reading too, with the additional error added in that two points had to be divided perfectly into 100 units! The inaccuracies were eventually corrected but with ever so slight deviations from the original scale(s) and forever a relic in our temperature measurement systems.
It hasn't frozen for many years so there are no accurate records.The only reliable records I can access show that the temperature in 1709 dropped to -15° C, (-5°F), and stayed that low for 11 days.Non-tidal parts of the Thames froze in 1963. That is the last time any part of the Thames froze.
In the winter of either 1982 or 1983 Nashville or Gallatin TN had a record breaking low of -25 degrees F. I lived in Gallatin at the time, and I woman I knew froze to death when her husband locked her out of the house.
Everthing froze, and got destroyed but many things preserved in the ice. Hope that helps! :)
They move at a slower pace until they stop and froze into place.
minus 40 degrees
Celsius was invented as a way of measuring temperature. A scientist named Anders Celsius put a thermometer in water until it froze, and marked where the mercury level was. He then measured the level in boiling water. The temperature in boiling water was given 100 Celsius, freezing was given 0 Celsius.
What is the differences of Celsius and Fahrenheit thermometer? Don's say centigrade, say degrees Celsius. Look for the differences yourself. Here is a nice temperature converter. Scroll down to related links and look at "Conversion of temperatures and formulas".
The teacher said that water froze at zero degrees Celsius.
Water freezes at 273 on the Kelvin scale. To covert Kelvin to Celsius, you subtract 273 from the Kelvin number, so 273 Kelvin is equal to 0 degrees Celsius, the freezing point of water.

The temperature was -40
He froze in his steps just like a deer in the headlights. The water on the bird bath froze last night when the temperature dipped below 30F. I almost froze to death without my jacket. She froze in terror and then let out a scream that would curdle milk. It was so cold outside his tongue froze to the flagpole when they dared him to lick it.
Although it is commonly thought that 98.6 degrees Fahrenheit is the average oral temperature for an adult, normal temperature can range from 97.1 degrees to about 99.5 degrees. It is a good idea to determine your own normal body temperature by taking your temperature when you feel well. This can also be done during your regular doctor's visit, but it is best to do it yourself for a few reasons: Different thermometers can have slightly different results, and body temperature can change with weather, time of day, and physical activity. To understand your body temperature, take your healthy temperature multiple times in a variety of conditions, using the same thermometer. Any temperature difference of more than a degree from your normal could be a fever.
Wow, that's a pretty freaky coincidence, that the freezing point of such a common substance just happens to be exactly 0 degrees, huh? Actually, the truth is that it's not a coincidence at all: it's because Anders Celsius defined his temperature scale using the freezing and boiling points of water, setting them at zero and one hundred degrees respectively.
