Wikipedia Meaning and Definition on 'Steam'
Steam is either mist (as seen from a kettle), or the gas phase of water (water vapor).
In common speech, steam most often refers to the visible white mist that condenses above boiling water as the hot vapor mixes with the cooler air. This mist consists of tiny droplets of liquid water. Pure steam emerges at the base of the spout of a steaming kettle where there is no visible vapor.
Pure steam is a transparent gas. At standard temperature and pressure, pure steam (unmixed with air, but in equilibrium with liquid water) occupies about 1,600 times the volume of an equal mass of liquid water. In the atmosphere, the partial pressure of water is much lower than 1 atm, therefore gaseous water can exist at temperatures much lower than 100 °C (212 °F) (see water vapor and humidity).[See more about Steam at Dictionary 3.0 Encyclopedia]

'Steam' in famous quotation sentence
* Imagination has brought mankind through the dark ages to its present state of civilization. Imagination led Columbus to discover America. Imagination led Franklin to discover electricity. Imagination has given us the steam engine, the telephone, the talking-machine, and the automobile, for these things had to be dreamed of before they became realities. So I believe that dreams--daydreams, you know, with your eyes wide open and your brain machinery whizzing--are likely to lead to the betterment of the world. The imaginative child will become the imaginative man or woman most apt to invent, and therefore to foster, civilization. - L. Frank Baum
