IGCSE Chemistry Notes on The Particulate nature of matter

• Cambridge IGCSE Chemistry Revision Notes  prepared by Cambridge trained staff with rich experience.

Syllabus Objectives:

Core

• State the distinguishing properties of solids, liquids and gases 
• Describe the structure of solids, liquids and gases in terms of particle separation, arrangement and types of motion
• Describe changes of state in terms of melting, boiling, evaporation, freezing, condensation and sublimation
• Describe qualitatively the pressure and temperature of a gas in terms of the motion of its particles 
• Show an understanding of the random motion of particles in a suspension (sometimes known as Brownian motion) as evidence for the kinetic particle (atoms, molecules or ions) model of matter 
• Describe and explain diffusion

Supplement

• Explain changes of state in terms of the kinetic theory
• Describe and explain Brownian motion in terms of random molecular bombardment 
• State evidence for Brownian motion 
• Describe and explain dependence of rate of diffusion on molecular mass
