Title: Does the high surface tension provides elasticity
Post by: erickejah on 04/02/2009 03:52:03

People can walk in mercury  [:o], thanks to its high surface tension.
If the same element is put at 4.3° it becomes solid:
1. would it retain the same surface characteristic?
2. If it retains the characteristic would it have elasticity?

They can't actually 'walk in' mercury. Only one person has sat on it (as far as I know anyway)

The reason you can 'sit' on mercury is because it is extremely DENSE; you float just the same as in water.
But there is an awful lot of 'upthrust' (most favouritest School Science word ever)- 13.6 times as much as water.
