Page 1States of matter - ReviewThe review page introduces the states of matter and differences (volume occupied, shape taken....) between them as well as giving names to the various changes of state. Questions ask the user to identify the state from its properties, from the temperature of the sample (given melting and boiling temperatures) and to name the various state changes.
Page 9Energy and change of state - ReviewThe review page highlights the change in the energy of the sample with the various changes of states. The questions following ask the user whether particular state changes release or absorb energy from the surroundings.
Page 13Particle view - ReviewThe review page shows a particle view of the three states of matter and describes differences in the speed of the particles and the extent of motion of the particles in the solid, liquid and gas state. The questions following highlight what happens at the particle level with various state changes including some where students identify which picture correctly represents at a particle level the specified state of a substance.
