Definitions for boiling point
This page provides all possible meanings and translations of the word boiling point
boiling point, boil(noun)
the temperature at which a liquid boils at sea level
"they brought the water to a boil"
being highly angry or excited; ready to boil over
"after an hour of waiting I was at the boiling point"
The temperature at which a liquid boils, with the vapor pressure equal to the given external pressure.
The boiling point of a substance is the temperature at which the vapor pressure of the liquid equals the pressure surrounding the liquid and the liquid changes into a vapor. A liquid in a vacuum has a lower boiling point than when that liquid is at atmospheric pressure. A liquid at high-pressure has a higher boiling point than when that liquid is at atmospheric pressure. In other words, the boiling point of a liquid varies depending upon the surrounding environmental pressure. For a given pressure, different liquids boil at different temperatures. The normal boiling point of a liquid is the special case in which the vapor pressure of the liquid equals the defined atmospheric pressure at sea level, 1 atmosphere. At that temperature, the vapor pressure of the liquid becomes sufficient to overcome atmospheric pressure and allow bubbles of vapor to form inside the bulk of the liquid. The standard boiling point is now defined by IUPAC as the temperature at which boiling occurs under a pressure of 1 bar. The heat of vaporization is the energy required to transform a given quantity of a substance from a liquid into a gas at a given pressure.
