Surface Tension

High Specific Heat

It takes a lot of heat to raise the temperature of water. It boils at 100 degrees Celsius

It also takes a long time for it to cool down, this keeps the earth’s temperature from being extreme.

Capillary action

Water and the things dissolved in it move up small spaces or tubes, even against gravity

Expands when it freezes

What would happen to all those fish if water sank when it froze?
