Jun 15, 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.
The boiling point of a substance is the temperature at which the vapor pressure of a liquid equals the pressure surrounding the liquid and the liquid changes into a vapor. The boiling point of a liquid varies depending upon the surrounding environmental pressure.

May 25, 2022 · The normal boiling point or the atmospheric boiling point is the boiling point at 1 atmosphere of pressure or sea level. The standard boiling point, as defined by the IUPAC in 1982, is the temperature at which boiling occurs when the pressure is 1 bar.
Jul 15, 2023 · 10.12: Boiling Point. When we heat a liquid until it boils, the bubbles that form inside the liquid consist of pure vapor. If the liquid is well stirred while boiling occurs, the vapor in the bubbles will be in equilibrium with the liquid and will have a pressure equal to the vapor pressure at the boiling temperature.
May 6, 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.
Aug 6, 2020 · The normal boiling point of water is 100 °C, 212 °F, or 373.1 K. The “normal” refers to sea level or an elevation of 0 meters or feet. But, the boiling point of water changes with elevation. The boiling point is a higher temperature below sea level and a lower temperature above sea level.
Jan 30, 2023 · Boiling is the process by which a liquid turns into a vapor when it is heated to its boiling point. The change from a liquid phase to a gaseous phase occurs when the vapor pressure of the liquid is equal to the atmospheric pressure exerted on the liquid.
The boiling point of a compound is the temperature where the liquid-gas phase change occurs. In more technical terms, it is when a liquid's vapor pressure equals its applied pressure (typically the atmospheric pressure).
Nov 27, 2016 · Boiling point is a key property of matter in which the vapor pressure of a liquid equals the pressure around the liquid and the liquid turns into a vapor. The boiling point of a substance is highly dependent on the environment around the substance.
