Water, the most important substance that comes from the earth, has many observable properties that make it one of the most amazing liquids known to mankind. Not only is it necessary for the survival of humans and animals, but also it is one of the few liquids that can dissolve many different types of solids.

 Water is also the only material that is found naturally on the Earth's surface in all three states of matter: liquid, solid, and gas. Let's take a look at water's many properties.
 
Water has transparency, which means that you are able to see clearly through water. This is one property that allows scientists to determine if certain solids have completely dissolved in water. Another property of water is shapelessness. Since water takes on the shape of its container, it can be used to measure the volume of irregular objects.
 
Water also has movement or flow.  Water always flows downhill unless there is a force or machine to push it uphill. The steeper or more slanted the hill, the faster the water will flow down that slope or hill.
