Water will boil at 212 degree Fahrenheit and freezes at 32 degree Fahreneheit. In Celsius, it boils at 100 degrees and freezes at 0 degrees. These temperatures determine how hot or cold a substance is.
It depends. Pure water will boil at 212 degrees Fahrenheit at sea level. Impurities and air pressure will change that. The higher you go above sea level the less air pressure you get and thus boiling point is lowered. Impurities will usually raise the boiling point.
