Nature of Matter

Nature of Matter. All of the materials around you are made up of matter. You are made up of matter, as are the chair you sit on and the air you breathe. 1. Give an example of solid matter. 2. Give an example of liquid matter. 3. Give an example of gaseous matter. 4. Is all matter visible?

The Nature of Matter

The Nature of Matter. Liquids. The ability of gases and liquids to flow allows then to conform to the shape of their containers. Liquids are much more dense then gases. More on liquids…. Increasing the pressure on a liquid has hardly any effect on its volume. (The same is true of solids).
