IGCSE Chemistry : The particulate nature of matter (Topical questions and Mark scheme )

Suitable for all IGCSE CAIE students and teachers.

This is the updated version with updated information and questions. Students can revise and master the topic from the useful and incredible resources.

It covers the following learning objectives:

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