- the temperature at which a liquid boils at a given pressure, usually atmospheric pressure at sea level; the temperature at which the vapour pressure of a liquid equals the external pressure
- informal the condition of being angered or highly excited
- The temperature at which a liquid changes to a vapor or gas. This temperature stays the same until all the liquid has vaporized. As the temperature of a liquid rises, the pressure of escaping vapor also rises, and at the boiling point the pressure of the escaping vapor is equal to that exerted on the liquid by the surrounding air, causing bubbles to form. Typically boiling points are measured at sea level. At higher altitudes, where atmospheric pressure is lower, boiling points are lower. The boiling point of water at sea level is 100°C (212°F), while at the top of Mount Everest it is 71°C (159.8°F).
A climax or crisis; a high degree of fury, excitement, or outrage. For example, The union's disgust with management has reached the boiling point. This metaphoric term alludes to the temperature at which water boils. [Second half of 1700s]
have a low boiling point. Become angry quite readily, as in Don't tease her anymore—she has a low boiling point. This phrase means that it takes less heat than usual for a boiling point to be reached. [First half of 1800s] Also see boil over; make one's blood boil.
