Year 10 Kinetic Theory and Pressure

We saw this model of atoms in the air. The tiny metal ball bearings are like the atoms and they are constantly moving at high speed. The fact that atoms are always moving is called KINETIC THEORY. In the picture above, the atoms crash at high speed into the polystyrene block. This pushes the block up. Pressure in the air exists because atoms in the air are crashing into objects at high speed all the time.
