boiling point in Science
boiling point
  (boi'lĭng)   
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).
