What Temperature Does Water Boil at and Has it Changed?

[93truck]

I always thought it was at 212 F . My 7 year old teacher is teaching them 215 F. When did this change. I am sorry in advanced if this is in the wrong section.

It is 100 C or 212 F at standard (1 atm.) pressure. Your teacher is incorrect.

It must be just to be a number easier to work with or something. It's not that grave IMO

Your teacher is incorrect.

Perhaps she lives in Holland? Or the Dead Sea? Or any of http://en.wikipedia.org/wiki/List_of_places_on_land_with_elevations_below_sea_level" ?

Yeah, and pi=3...

Your teacher is seven years old >.<"...?

O and, pi doesn't equal 3, but until your 14, apparently its 22/7 >.<"

Actually, 22/7 is quite a good estimate; it is accurate to within 4 parts in 1000.

thats a nicer way of saying 2 decimal places. The truth is that it is an infinite number of decimal places off and students think its exactly 22/7.

at least try 355/113

Since this thread has degenerated into some absurd discussion that has nothing to do with the OP, I will assume that the discussion on the original topic is done.
