WHAT IS THE BOILING POINT<\/h2>\n

The boiling point is simply defined as the temperature at which the change of state of an element from liquid to gas occurs. More precisely, the boiling point is the temperature at which the vapour pressure of a liquid equals the vapour pressure of the medium in question. In other words, when defining the boiling point, the ambient pressure must be taken into account.<\/p>\n

BOILING AND MELTING POINT OF WATER<\/h2>\n

The standard boiling temperature of water (at 1 atm) is 100\u00b0C.<\/p>\n

However, the boiling point depends directly on the atmospheric pressure. Thus for water we have different boiling points at sea level (atmospheric pressure approx. 1 bar), on a mountain 8000 metres (atmospheric pressure 0.3-0.4 bar), or in a pressure cooker (pressure 1.5 bar).<\/p>\n
