Still not sure about the maths though. Does it neccessarily follow that a decrease in density of (say) 6% will lead to an equal (6%) increase in volume? It seems to make sense but my head's a bit foggy 
Oh, and sorry if it seems like the thread's been hijacked. It hasn't, well - not really anyway |
A decrease in density of 6% will result in an increase in volume of around 6.38 %.
There are some statistics about this at
http://www.simetric.co.uk/si_water.htm
More than 70 % of the Earth's surface is covered with about 1.36 billion cubic kilometers of water / ice of around 2% of this is in ice form.
No, don't think the thread has been hijacked at all, just developed into serious discussion on a very important subject.
The wind here is still rattling the windows round here, it's amazing how much it seems to make the double glazing in the patio doors bulge.
