Water & Ice at 4o Centigrade...

[RascalPuff]

H2 0 @ 4o Centigrade:

A conspicuous exception to very specific rules...

The rule is that when heat is applied to matter - it expands to some degree.

When heat is subtracted from matter - it contracts to some degree.

Exception to this fundamental rule is, whether heat is added to or subtracted from matter @ 4o C. - that matter expands, however slightly (even when heat is subtracted from it) before it then conforms to the rule of expansion with added heat.

I don't purport to know what this means, but, I submit that it means something in particular, and that, if that something in particular could be understood, it will reveal answers to previously dissolute questions, and/or introduce advanced questions with corroborating answers. That is, I think this paradoxical fact flags itself for further consideration.

Moreover, H 2 0 @ 4o C. alternately and ambivalently occurs as liquid water or solid ice.

Again, is there not a self revealed - apparenty unanswered - question here?

If there is some elementary - or complex - explanation for this, that is already understood, request that someone provide that explanation.
Thank you.

Thanks RP,you have indeed highlighted an anomaly which warrents further investigation
if this is an exception,then there must be a reason why!
