The three states of matter

Lesson Progress
0% Complete
  • There are three states of matter – solid, liquid and gas

  • All matter is made up of particles. These particles can be atoms, molecules or ions

  • The arrangement of these particles determines the structure and property of each state

  • The state of matter depends on how strong the forces of attraction are between the particles of the material

  • How strong the forces are depends on three things:

The material

The temperature

The pressure 

  • The kinetic theory is used to explain the arrangement and motion of particles in different states of matter

  • State symbols are often used in chemical equations¬†

  • (s) for solid

  • (l) for liquid

  • (g) for gas
