SUMMARY

Water boils at 100°C (212°F) at standard atmospheric pressure (1 atm). The claim that it boils at 215°F is incorrect and likely stems from a misunderstanding or simplification for educational purposes. The discussion also touches on the approximation of pi, where 22/7 is mentioned as a common estimate, although it is not exact. The conversation highlights the importance of accurate scientific education, particularly in fundamental concepts like boiling points and mathematical constants.

PREREQUISITES
  • Understanding of basic physics concepts, specifically thermodynamics.
  • Familiarity with the metric and imperial measurement systems.
  • Knowledge of atmospheric pressure and its effects on boiling points.
  • Basic mathematical concepts, including fractions and approximations.
NEXT STEPS
  • Research the effects of altitude on boiling points and how atmospheric pressure influences them.
  • Study the concept of significant figures and their importance in scientific measurements.
  • Learn about common mathematical approximations and their applications in education.
  • Explore the history of temperature measurement and the development of the Celsius and Fahrenheit scales.
USEFUL FOR

Students, educators, and anyone interested in understanding fundamental scientific principles related to temperature and measurement accuracy.

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

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.
