摘要

当沸腾发生时，气泡中的蒸汽将与液体处于平衡状态，其压力将等于沸腾温度时的蒸汽压。然而，气泡内部的压力也必须等于液体上方的外部压力。如果不是这样，泡沫要么会突然破裂，要么会突然膨胀。因此，当液体沸腾时，液体的蒸气压等于外部压力。

Boiling Point: 1961–1967

while boiling occurs, the vapor in the bubbles will be in equilibrium with the liquid and will have a pressure equal to the vapor pressure at the boiling temperature. However, the pressure inside the bubbles must also be equal to the external pressure above the liquid. If this were not so, the bubbles would either suddenly collapse or suddenly expand. It follows therefore that when a liquid boils, the vapor pressure of the liquid is equal to the external pressure.
