Remarks: Difference between Steam and Water Vapour
Steam is merely water vapour at a temperature equal to or greater than the boiling point. We cannot see water vapour; for the same reason, we cannot see steam.
When water is heated in a vessel with a nozzle, a cloud forms as the hot water vapour issuing from the nozzle mixes with the colder surrounding air. Such a cloud is popularly, although incorrectly, called “steam”. We cannot see steam, so what we can see is not rightly called steam. Call the cloud what you like, but just remember that it is composed of water droplets not water vapour. Like mixing cloud in meteorology, it is the mixing of moist air masses with different characteristics that yields such a cloud. If you heat the nozzle with a gas torch the cloud will soon disappear. Yet, water vapour is still issuing from the nozzle.
