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 />
