Depending on the physical state of an object, there are a couple ways to measure volume. Volume simply refers to the space an object takes up. Matter has two fundamental properties: volume and mass.

In the gaseous state, the particles are spaced out relative to one another and are moving around with rapid, random motion.Printable Version The Nuclear Regulatory Commission's Science 101: What is Matter?Įverything that exists is made up of matter.

In liquids, the particles are still tightly packed, but as well as vibrating, they can move over and in between one another.In solids, these particles are tightly packed together, usually in a regular array, and vibrate back and forth.

In order to explain how these properties come about, the kinetic-molecular theory has been developed.Īccording to this theory, all matter is made up of extremely small particles (atoms, molecules or ions), which are in constant motion: Solids, liquids and gases each have their own characteristic properties. Beach sand has a non-uniform composition, but the grains can be physically separated into mineral groupings.

How does golden beach sand fit into this system? Most of the grains of golden beach sand are either light-coloured feldspar or clear quartz.

The application of various separation techniques to this liquid yields numerous categories of chemical compound. Filtering the milk will separate out suspended solids (proteins and lipids), leaving behind a clear liquid.

How does milk fit into this system? Milk has a uniform composition, and it is a solution (homogeneous).

To see how this classification system works, let us take two examples:
