Hey - that's physics, not chemistry.

think nowadays we'd say maths or stamp collecting given much of modern
physics).

I stumbled across this while looking for the coefficient of expansion

I thank you for that link, it brought back a few memories.
I used to work in the Fire Brigade and, as you would expect, water plays a
major part in their activities. During lectures I often asked my class "why
cold water could be lifted (sooked up) from a greater lift than warmer
water" and "if heat rises, why does ice form on the surface of a pond and
not at the bottom".
This link explained it technically but would go over the head of most of the
students. The samples were only used as a point of interest.
Sorry for going OT a bit
Bill
