Water as a Liquid ü The definition of a liquid is matter (something) which has a definite volume and no definite shape. ü A liquid takes the shape of its container. ü In a liquid, molecules move and slide around each other.

Liquid water is found in many places • You see liquid water coming out of the faucet, • when it rains, • and running in a river. .

Ice, snow, and frost are examples of water in the solid state. • During Winter, we see a lot of water in solid form. • Other examples of solid water are ice cubes, icicles, ice on a skating rink.
