Question
What is the boiling point of pure water at normal
atmospheric pressure (sea level)?Solution
Pure water at normal atmospheric pressure (about 1 atmosphere at sea level) boils at 100∘C . At this temperature, water molecules have enough energy to escape from the liquid phase and form bubbles of vapor within the water, which rise to the surface and burst. This process is called boiling.
