How much do you know about water?

Part 1

Physical properties of solids

> Fixed volume - cannot be compressed

> Fixed shape

> Cannot flow

> High density

Physical properties of liquids

> Fixed volume - cannot be compressed

> No fixed shape - takes the shape of the container it occupies

> Can flow

> High density

Physical properties of Gases

> No fixed volume - can be compressed

> No fixed shape - completely fill up and take the shape of their containers

> Can flow

> Low density

Why does water not freeze at the bottom of the lake?
