WebLiquids with high vapor pressures have lower boiling points and therefore lower activation energies. The boiling point is the temperature at which the vapor pressure equals atmospheric pressure, such that the pressure of the atmosphere can no longer hold the liquid in a liquid state and bubbles begin to form. WebA liquid will boil when its vapor pressure equals atmospheric pressure. Water’s normal boiling point is 100°C. At this temperature the vapor pressure of water is equal to 101 kPa, standard atmospheric pressure. If we were in a location with a different atmospheric pressure the boiling point would be different.
