Boiling is the method of cooking food in boiling water or other water-based liquids such as stock or milk. [ 13] Simmering is gentle boiling, while in poaching the cooking liquid moves but scarcely bubbles. [ 14] The boiling point of water is typically considered to be 100 °C (212 °F; 373 K), especially at sea level.
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. A liquid in a partial vacuum, i.e., under a lower pressure, has a lower ...

Death by boiling. Death by boiling is a method of execution in which a person is killed by being immersed in a boiling liquid. While not as common as other methods of execution, boiling to death has been practiced in many parts of Europe and Asia. Due to the lengthy process, death by boiling is an extremely painful method of execution.
Nucleate boiling. In fluid thermodynamics, nucleate boiling is a type of boiling that takes place when the surface temperature is hotter than the saturated fluid temperature by a certain amount but where the heat flux is below the critical heat flux. For water, as shown in the graph below, nucleate boiling occurs when the surface temperature is ...
Boiling-point elevation. Boiling-point elevation is the phenomenon whereby the boiling point of a liquid (a solvent) will be higher when another compound is added, meaning that a solution has a higher boiling point than a pure solvent. This happens whenever a non-volatile solute, such as a salt, is added to a pure solvent, such as water.

Vapor pressure[ a] or equilibrium vapor pressure is the pressure exerted by a vapor in thermodynamic equilibrium with its condensed phases (solid or liquid) at a given temperature in a closed system. The equilibrium vapor pressure is an indication of a liquid's thermodynamic tendency to evaporate. It relates to the balance of particles escaping ...
