The word 'vapour' is used to describe a substance that is in a gaseous state, but not necessarily the same as air. It can refer to steam or water vapor, as well as other gases that are produced from liquids or solids. It is important to note that vapour is not the same as smoke or fumes, which are created from combustion and can be harmful to breathe. Some examples of vapour include the steam that comes off of boiling water, the mist that rises from a waterfall or the fog that forms on a cool morning. The word 'vapour' is most commonly used in science, but it can also be used in everyday conversation when talking about the atmosphere or different forms of gas.
