Solids, Liquids and Gases
The Particle Model
Particles are the fundamental units that make up all substances. The substances can be in one of three different states; solids, liquids and gases.
The arrangements and energies of the particles will affect the density of each state of matter.
Comparing Solids, Liquids and Gases
Below is a table showing the three states of matter and information about each one. For exams, you will be expected to be able to recognise and draw the diagrams shown below.
