Water in boiling, the phenomenon of the water is tumbling, precipitation of bubbles, the phenomenon of the water surface is tumbling and bubbles, the phenomenon of the water surface above the water mist on the water mist is condensed water vapor.

Inside and on the surface of the liquid at the same time, violent vaporization occurs. Different liquids have different boiling points. Even for the same liquid, the boiling point varies with the external atmospheric pressure. Also, the word has many different meanings, the most common being crowd excitement and euphoria.

Boiling water kills any microorganisms that may be present, thus making the water drinkable. Different microorganisms have different sensitivities to heat, but if the water is kept at 70°C (158°F) for 10 minutes, many microorganisms will be killed, but some are more resistant to heat. Clostridium difficile can withstand this treatment, but since infections caused by this microbe are not waterborne, this is not a problem.

Cautions:

Boiling occurs at a certain external pressure, only at a certain temperature (boiling point), and only under constant heat. When a liquid boils, its temperature remains constant and it still absorbs heat. The saturated vapor pressure is the same as the external pressure P.

When the external pressure increases, the boiling point of the liquid rises; otherwise, it decreases. Different liquids have different boiling points at the same pressure. It is related to the saturation vapor pressure of the liquid. When the saturated vapor pressure at the current temperature is the same as the outside world, the liquid will boil, and the saturated vapor pressure of the liquid is positively correlated with the temperature of the liquid.
