STUDY NOTES / THE PARTICULATE NATURE OF MATTER
Note:

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
