Answer 2

$\huge\mathfrak\color{blue}{Answer}$

When the atmospheric pressure is equal to the vapor pressure of the liquid, boiling will begin. When a liquid boils, what is inside the bubbles? The bubbles in a boiling liquid are made up of molecules of the liquid which have gained enough energy to change to the gaseous phase.
