The four fundamental states <strong>of</strong> matter<br />

We are all familiar with solids, liquids and gases, but have we ever heard <strong>of</strong> these with the term ‘plasma’<br />

mentioned as well? Plasma belongs here as it is also a form <strong>of</strong> matter. Altogether, these four states <strong>of</strong> matter are<br />

associated with every form <strong>of</strong> physical thing we can see or think <strong>of</strong> in our world and in our universe.<br />

<strong>Our</strong> four states <strong>of</strong> matter are (1) plasma (2) gas (3) liquid (4) solid.<br />

To help with drawing mental pictures, I will base the following<br />

explanations around something we are all familiar with by referring<br />

throughout to the various forms in which find water and to its constituent<br />

elements. Water is a molecule H 2 O that has two atoms <strong>of</strong> hydrogen and<br />

one atom <strong>of</strong> oxygen.<br />

‘Solid’ is the fourth state <strong>of</strong> matter. Water ice, just like iron or diamond,<br />

is considered a solid because its molecules are aligned rigidly in a<br />

crystalline structure. Ice forms at 0˚Celsius (Centigrade) because the<br />

heat energy contained in the atoms <strong>of</strong> hydrogen and oxygen that form<br />

55 | Some basic theory that will help<br />

its molecules is very low. In other words, the electrons <strong>of</strong> the atoms that make up<br />

the water molecules are not oscillating with enough energy to cause breakage to the<br />

bonds they form between the molecules <strong>of</strong> the crystalline structure, so everything is<br />

held together to produce solid ice.<br />

‘Liquid’ is the third state <strong>of</strong> matter. When the temperature <strong>of</strong> ice rises to just above<br />

0˚C it begins to melt and become liquid water. This process occurs because the heat<br />

energy contained in the atoms has increased enough for electrons to begin breaking<br />

the bonds between the molecules <strong>of</strong> the crystalline structure <strong>of</strong> the ice. In other<br />

words, the energetic oscillations <strong>of</strong> the electrons <strong>of</strong> the hydrogen and oxygen atoms<br />

<strong>of</strong> the water ice molecules have been increased to a great enough level through<br />

the application <strong>of</strong> external energy, that separation takes place between the intermolecule<br />

bonds. This can also be seen as an overall increase in energy stored within<br />

the ice structure. A general point to make here is that because the molecules are less<br />

restricted, liquids are considered to be ‘less mechanically stable’ than solids.<br />
