Boiling or ebullition is the rapid phase transition from liquid to gas or vapour; the reverse of boiling is condensation. Boiling occurs when a liquid is heated to its boiling point, so that the vapour pressure of the liquid is equal to the pressure exerted on …

2023年1月30日 · 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.

2025年2月18日 · boiling, the cooking of food by immersion in water that has been heated to near its boiling point (212 °F [100 °C] at sea level; at higher altitudes water boils at lower temperatures, the decrease in boiling temperature being approximately one degree Celsius for …

The meaning of BOILING is heated to the boiling point. How to use boiling in a sentence.

2025年2月18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 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 A liquid boils at a temperature at which its vapor pressure is equal to the pressure of the gas above it. The lower the pressure of a gas above a liquid, the lower the temperature at which the liquid will boil.

2019年9月5日 · Boiling is defined as a phase transition from the liquid state to the gas state, usually occurring when a liquid is heated to its boiling point. At the boiling point, the vapor pressure of the liquid is the same as the external pressure acting upon its surface.

2025年3月21日 · The normal boiling point is the temperature at which the vapor pressure of the liquid is equal to standard pressure. Because atmospheric pressure can change based on location, the boiling point of a liquid changes with the external pressure.

Boiling is the process of rapidly converting a liquid to its gaseous (vapor) state, typically by heating the liquid to a temperature called its boiling point. The boiling of a substance is known as a phase change or phase transition .
