	<onlyinclude>'''Boiling point''' is the [[temperature]] that a [[liquid]] will [[phase change\|change phase]] into a [[gas]]. Boiling occurs when the [[~~vapor~~ pressure]] of a liquid is equal to the atmospheric [[pressure]] of the gas outside of it.</onlyinclude> Because of this, as the outside pressure changes so does the boiling point of the liquid. Therefore there is a set pressure known as a [[standard atmosphere]] (atm) which determines what is called the ''normal boiling point'' of a liquid. For example, [[water]]'s normal boiling point is [[celsius\|100<sup>o</sup>C]], which occurs when the atmospheric pressure is exactly 1 atm. If the atmospheric pressure is less than 1 atm, the boiling point of the liquid will decrease, as is the case at higher altitudes on Earth. And if the atmospheric pressure is greater than 1 atm, such as in a pressure cooker, the boiling point will begin to increase drastically.<ref name=chem>Purdue Chemistry, ''Boiling'' [Online], Available: https://www.chem.purdue.edu/gchelp/liquids/boil.html</ref>		<onlyinclude>'''Boiling point''' is the [[temperature]] that a [[liquid]] will [[phase change\|change phase]] into a [[gas]].
