Discussion Overview

The discussion centers around the boiling point of water, specifically questioning whether it has changed from the commonly accepted value of 212°F (100°C) at standard atmospheric pressure. Participants express confusion regarding a claim made by a teacher that the boiling point is 215°F.

Discussion Character

  • Debate/contested
  • Conceptual clarification

Main Points Raised

  • One participant asserts that the boiling point of water is 100°C or 212°F at standard pressure, claiming the teacher is incorrect.
  • Another participant suggests that the teacher's figure of 215°F might be a simplification for easier understanding.
  • Some participants humorously note the teacher's age and question the validity of the information being taught.
  • There is a side discussion about the value of pi, with one participant mentioning that 22/7 is a common approximation, while another points out its inaccuracies.
  • A participant expresses frustration that the conversation has strayed from the original topic.

Areas of Agreement / Disagreement

Participants generally disagree on the accuracy of the teacher's claim regarding the boiling point of water, with no consensus reached on the matter. The discussion also diverges into unrelated topics, indicating a lack of focus on the original question.

Contextual Notes

Some participants reference geographical locations that might affect boiling point due to elevation, but this is not fully explored. The discussion also touches on the teaching of approximations in mathematics, which may not directly relate to the boiling point issue.

Who May Find This Useful

This discussion may be of interest to educators, students learning about the properties of water, and those curious about the teaching of scientific concepts.

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.
 
Physics news on Phys.org
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.
