Warming oceans are currently the leading cause of sea-level rise, since water expands as it warms.

Then why does an Ice cube tray expand/protrude when the full cube bin water freezes ?

And conversely why does water boil over a pan.

Damned good questions.

Well here are the answers via this Calculator

I input Temps of 40 starting and 20 finishing resulting in a change of .0986/.0014

20 starting and 40 finishing resulting in a change of .101/-.0014

The change in Volume is the same both ways.

Cool calculator.

Oh and the unusual expansion of H2O upon freezing is because of the polarity of the molecules.
