Snow, like all other matter can get as cold as it's environment. Snow cannot rise above water's freezing point, because it would be liquid water. To expect snow to stay at it's freezing point is like expecting wax to never get colder a than it's freezing point. There is no basis for snow staying at 32 degrees F.
Ice can be colder than zero degrees centigrade; there is no law that keeps ice at zero degrees. If there were such a law, then ice would be a perfectly clean, infinite source of energy. We could simply pump heat out of ice, and the heat would never diminish. But this is not the case. So it is possible to add water ices of different temperatures and in the long run the temperatures would balance out.
I think the term you're looking for is cryogenic processing. The NIST defines cryogenic temperatures as those below 93.2 Kelvin. Slowly reducing temperatures, to prevent damage from thermal shock, to below 93.2 Kelvin is a cryogenic process.
Hawaii is the only state in the United States that has never recorded a temperature of 100 degrees Fahrenheit or more. This is due to its oceanic climate and the moderating effects of the surrounding ocean.
Yes, the boiling point of water is normally at 100 degrees Celsius
No, the sun is never directly overhead at midday in Memphis, Tennessee, as it is located at a latitude of around 35 degrees north. The sun is only directly overhead at latitudes between the Tropic of Cancer (23.5 degrees north) and the Tropic of Capricorn (23.5 degrees south).
Never because the 4 interior angles of any quadrilateral always add up to 360 degrees
always
is an exterior angle of a quadrilateral always sometime or never 90 degrees
north and south pole
They are never the same, they always differ by 273.15 degrees.
No. In fact, they never are. A right angle by definition is 90 degrees. An obtuse angle is any degree greater than 90. In order for two angles to be supplementary, they must equal 180 degrees. Because an obtuse angle is always greater than 90 degrees, and a right angle is always 90 degrees, an obtuse angle and a right angle can never be supplementary.
Sometimes when its vertex angle is 90 degrees and the other 2 angles each measure 45 degrees
A rhombus is sometimes a square but a square is always a rhombus. A square is a rhombus with all angles equal to 90 degrees.

Always because they have to be 90 degrees, but it could be sometimes I guess if you factor in their different sizes.
It never was. It has always lived in the wild and was never extinct. it currently has the "least concern" label from the ICUN. The population has been growing steadily.
You would never see Polaris there because it would always be 41 degrees or more below the northern horizon. On the other hand you can see many fine stars and constellations that are never seen in North Europe or the north of the USA and Canada.
