Boiling point - Wikipedia
The boiling point of a substance is the temperature at which the vapor pressure of a liquid equals the pressure surrounding the liquid [1] [2] and the liquid changes into a vapor. The boiling point of a liquid varies depending upon the surrounding environmental pressure.
Boiling point | Definition, Examples, Temperature, & Facts
2024年11月15日 · Boiling point, temperature at which the pressure exerted by the surroundings upon a liquid is equaled by the pressure exerted by the vapor of the liquid; under this condition, addition of heat results in the transformation of the liquid …

The boiling point is the temperature at which the vapor pressure of a liquid is equal to the external pressure. As the altitude increases, the boiling point decreases.
Boiling Point of Gases, Liquids & Solids - American Elements
What is a boiling point? The boiling point of a substance is the temperature at which the vapor pressure of the liquid is equal to the surrounding atmospheric pressure, thus facilitating transition of the material between gaseous and liquid phases.
10.12: Boiling Point - Chemistry LibreTexts
2023年7月15日 · If this pressure is the standard pressure of 1 atm (101.3 kPa), then the temperature at which the liquid boils is referred to as its normal boiling point. This is the boiling point which is usually quoted in chemical literature. Not everyone lives at sea level, though.
Boiling point - Simple English Wikipedia, the free encyclopedia
The boiling point of a substance is the temperature at which the substance boils, or enters a state of rapid evaporation. For pure water this is 100° Celsius or 212° Fahrenheit , at standard pressure .
