Science glossary film: Boiling point

The temperature at which a liquid changes to a gas, at atmospheric pressure. This occurs at a specific temperature for each pure substance and is affected by pressure. Under normal conditions water boils at 100°C, whereas the gases in our atmosphere boil at temperatures around -190°C.
