Answer and see the solution →The diagrams below show the arrangement of particles in three different states of matter.
Arrangement of particles in three states of matter (a)[1 mark]Identify which numbered group of circles (1, 2 or 3) represents a gas.
(b)[2 marks]State two differences between the arrangement and movement of the particles in a solid and those in a gas.
(c)[1 mark]Explain why solids are not easily compressed.
