So its a Sunday morning and there I am in the figure hugging underware only, waiting for the kettle to boil for the first ( and probably best) cup of tea when I am reminded, apropos bugger all, about what my Physics teacher told me regarding steam.
What we see as steam gushing forth from the spout of a boiling kettle isn't steam at all but is in fact water vapour. Steam is an invisible gas and if you look at the boiling kettle's spout once again you will notice that there is a small gap between the spout and where the 'steam' seems to start. This area, where you can see nothing is the bit where the steam is. It then comes into contact with the colder air and condenses to form water vapour which we plebs misname 'steam'.
Dennypoos.............educational as hell, though a tad random.
