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.
Hawaii temperatures have never reached 100 degrees
The Green House effect is important because there is a kind of gas that forms a "blanket" around Earth that holds heat in the atmosphere and keeps Earth's atmosphere at a temperature that is comfortable for most living things. So without it the temperature would go down to 50 degrees Fahrenheit (32 degrees Celsius) colder than it is. That would cause all water to freeze and the planet to turn into an ice cube. The earth would become a very large iceberg. The atmosphere would always be below freezing. All that ice reflects heat back into space so the earth would never warm up.
Yes, the boiling point of water is normally at 100 degrees Celsius
the arctic ocean
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
Yes, LA has a winter, it just doesn't get much colder than 60 degrees during the day and almost never snows there.
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.
High temperature always flows to low temperature, never the other way around.
