Structure of matter and kinetic theory: JAMB Physics Past Questions and Answers

What the JAMB syllabus covers in Structure of matter and kinetic theory

Our summary: Atoms and molecules, and how the kinetic theory explains gas pressure, diffusion and changes of state.

• Molecular nature of matter ((i) atoms and molecules; (ii) molecular theory: explanation of Brownian motion, diffusion, surface tension, capillarity, adhesion, cohesion and angles of contact etc; law of definite proportion; (iii) examples and applications.)
• Kinetic theory ((i) assumptions of the kinetic theory; (ii) using the theory to explain the pressure exerted by gas, Boyle's law, Charles' law, melting, boiling, vaporization, change in temperature, evaporation, etc.)

Objectives

• differentiate between atoms and molecules;
• use molecular theory to explain Brownian motion, diffusion, surface tension, capillarity, adhesion, cohesion and angle of contact;
• examine the assumptions of kinetic theory;
• interpret kinetic theory, the pressure exerted by gases, Boyle's law, Charles' law, melting, boiling, vaporization, change in temperature, evaporation, etc.
