Boiling point definition science
WebThe boiling point corresponds to the temperature at which the vapor pressure of the substance equals the ambient pressure. Thus the boiling point is dependent on the pressure. Usually, boiling points are published with respect to standard pressure (101325 pascals or 1 atm ). At higher elevations, where the atmospheric pressure is much lower ... WebAn extreme case is a geyser, where you have a tall and narrow vertical path that prevents convection. The bottom heats to way above 100 °C (212 F) because of the pressure, and when it reaches the bubble point. At this point the pressure drops because some of the water on the top is expelled out or the bore is larger at the top.
