The boiling point of a substance is the temperature at which it changes state from liquid to gas throughout the bulk of the liquid. At the boiling point molecules anywhere in the liquid may be vaporized.

The boiling point at normal atmospheric pressure (1 atm, 14.7 psi, 101.325 kPa, 760 torr, 760 mmHg, 29.92 inHg1.01325 bar ) for some common fluids and gases can be found from the table below:
