States of Matter

This GCSE chemistry topic, states of matter, is all about solids, liquids and gases. You will have learnt about solids, liquids and gas for KS3 Science and this topic at GCSE builds on that knowledge. You need to know about particle arrangement and how heat energy affects the distribution of these particles in each state of matter. Whether you are revising KS3 chemistry or you are preparing for your GCSE exams, the resources below should be helpful.
