1. The kinetic theory explains the properties of the different states of matter. 2. All the particles in a solid liquid and gas are the same, the only thing that changes, is the amount of energy they have (turbine drawing). 3. Solids have a low amount of energy, too low to overcome the strong bonds that hold the particles together in a regular pattern, but not too low to stop movement all together, as they still vibrate about a fixed position. Solids are also incompressible because there is no free space for the particles to move into. If we give a solid some more energy, it will eventually loosen the bonds between the particles and allow them to move over each other and take the shape of its container, which is what we call a liquid. Similarly, liquids cannot be compressed because there are no free spaces between the particles. Which is why, if you were to jump of a really high diving board, the particles in the water below would for a split second represent the properties of concrete because the particles haven't had time to move out the way for the unfortunate diver. Gases have a lot of energy and move about their container very quickly and unlike solids and liquids, they can be compressed because there is lots of space for the particles to move into. Which is how a paintball gun works, by compressing the air very closely inside a tank and releasing it 4. in a short burst to propel the projectile onto someone's backside. OUCH!
