Wonder if the pressure from the coming glacial period will cause Yellow Stone to blow.

A phase state change, such as freezing, requires energy.

Hot water does not "always" freeze faster than cold water.
You are referring to the mpemba effect and it only occurs sometimes. There is still great debate as to why is happens. Science still can't explain why water expands when it freezes either.

It did when I was at school and still does over here in the UK it's due to crystallisation where the molecules of water iare further apart than they are in liquid form.
Sorry to do this but DUH! the amount of ignorance about science in this thread has reached the annoying point.

A phase state change, such as freezing, requires energy, that is why hot water freezes more rapidly in your refrigerator than cold water. (You can confirm this yourself with a simple experiment.) The Great Lakes have started freezing recently due to a combination of increased heat (energy) and the shifting of the jet stream due to low pressure systems forming in the west of North America due to, yes, global warming.

This frozen Great Lake reminds me of the time they stocked white tail deer on mackinac island. The first winter after the stocking, the lake froze and the deer walked off the island. Bbwwahahahaha
