What is caused by condensation of water vapour?


Foggy windows; reduced vision out of your windscreen; an annoying wait on a cold morning, when you get in your motor and have to turn the demister on full blast while the engine is still warming up.

And what else? Clouds in the air; rain falling from the sky? Street urchins painting rude signs on your windscreen with their fingers?
