Boiling water. Coloured macrophotograph of escaping bubbles of steam in boiling water. A liquid boils when bubbles of vapour form throughout its volume. This occurs at a certain temperature, which depends on the nature of the liquid and the atmospheric pressure. Pure water boils at 100 degrees Celsius at the standard atmospheric pressure of 10,1325 pascals. Magnification unknown.
