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.
25 Μαΐ 2022 · Learn what boiling point is, how it depends on pressure and purity, and how to measure it. See the normal and standard boiling points of the elements and the difference between boiling and evaporation.
4 Οκτ 2024 · boiling point, temperature at which the pressure exerted by the surroundings upon a liquid is equaled by the pressure exerted by the vapour of the liquid; under this condition, addition of heat results in the transformation of the liquid into its vapour without raising the temperature.
6 Αυγ 2020 · Learn what temperature water boils at different elevations and atmospheric pressures. Find out how to boil water at room temperature and why water freezes or boils in space.
6 Μαΐ 2019 · The boiling point is the temperature at which the vapor pressure of a liquid equals the external pressure surrounding the liquid. Therefore, the boiling point of a liquid depends on atmospheric pressure. The boiling point becomes lower as the external pressure is reduced.
13 Αυγ 2024 · If you want a quick and simple answer, you can say that the boiling point of water is 100 °C or 212 °F at 1 atmosphere of pressure (sea level). However, the value is not a constant.
15 Ιουλ 2023 · 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.
