Concepts of matter: WAEC Physics Past Questions and Answers

What the WAEC syllabus covers in Concepts of matter

Our summary: What matter is made of, its three states, and how the particle picture explains everyday behaviour.

• Concepts of matter (Simple structure of matter should be discussed. Three physical states of matter, namely solid, liquid and gas should be treated. Evidence of the particle nature of matter e.g. Brownian motion experiment, kinetic theory of matter. Use of the theory to explain: states of matter (solid, liquid and gas), pressure in a gas, evaporation and boiling; cohesion, adhesion, capillarity. Crystalline and amorphous substances to be compared (arrangement of atoms in crystalline structure to be described e.g. face centred, body centred).)
