The normal boiling point of a liquid is defined as?
the temperature at which its vapour pressure equals the atmospheric pressure
the temperature at which bubbles begin to form

the temperature at which the space above the liquid is saturated
Објашњење
The boiling point of a substance is the temperature at which the vapor pressure of a liquid equals the pressure surrounding the liquid and the liquid changes into a vapor.
