(a) compare the physical properties of solids, liquids and gases

(b) use the kinetic particle model to describe the different states of matter (solids, liquids and gases), relating their physical properties to the arrangement and motion of the particles (e.g. molecules, atoms) and the forces and distances between particles

(c) infer from a Brownian motion experiment the evidence for the random movement of molecules in a liquid or gas

(d) relate the rise in temperature of a body to the increase in average kinetic energy of all the particles in the body

(e) explain the pressure of a gas in terms of the motion of its particles.
