Why is boiling occurs when the saturated vapor pressure equals the external air pressure?
Thread Content
I’ve read many explanations; boiling occurs when the pressure inside the bubbles equals the external pressure. But why is saturated vapor pressure used in the definition? The definition of saturated vapor pressure is that it refers to the pressure exerted by the vapor on the liquid when both the gas and liquid phases are in thermal equilibrium in a closed environment. Therefore, I’m confused as to whose saturated vapor pressure is meant by the term used in the definition
This should be the definition of boiling in thermodynamics; after all, any physical phenomenon needs a definition so that it can serve as a basis for discussion and research.
The saturated vapor pressure of the liquid at that temperature
