>>>Besides, what is your defo. of "steam" - the white opaque vapour in a turkish bath or the invisible matter that issues from a kettle's spout and becomes the above?

>>It's the same thing - the only difference is in the ambient temperature and whether it's condensing or not. But water in the air is water in the air.

>I seem to recall our physics teacher defining the difference: The super hot invisible stuff is steam - the opaque mass is "water vapour" - or summat like that (it was a long time ago).

And the means of distinguishing them are in the eye of beholder, or the ambient temperature, or what? Chemically and physically, they are H2O molecules in the air; now whether they are forming droplets or not may be the difference, but only in what it's doing, not in what it is.

>>>Heh, I've just looked some up and, to add more confusion, you can get oil, electric or "gas boilers" - for the Dragans in us this would suggest they boil gas FGS!
>>
>>Are there any other FGs but gas FGs nowadays? I think there used to be wood FGs once upon a time, but never saw one.

>Don't know what your FG stands for - but you can get wooden FEGs - such as a totem pole, or in "the Wicker Man"

You efgeed first. You show yours first. I actually have no clue what an efgee is.
