the water will not sterilize if you boil the water! the water still has bacteria in the water even if you heat it up; that's because some bacteria is heat resistant and will not die through the process.
you don't even have to boil it you can buy spray that will disinfect it for you.
you boil it in water
How long it takes water to boil depends on how much heat is being used. Water boils at 100 degrees C
If you boil it, the water will evaporate. If you leave it boiling long enough, you should only have salt left.
a) if the water is PERFECTLY sterile and the bottle is PERFECTLY closed, the water would stay sterile years and years and years. b) but if the water in the bottle is not 100% sterile or the bottle is not 100% closed (which is more likely) some germs & co migth slowly multiply ... as their number is expected to be relatively low, you can consider the water to be sterile (or at least the number of the little creatures to be nonrelevant) up until the date on the bottle
