IGCSE Chemistry Edexcel 4CH1

1: (a) States of matter

#1.1

understand the three states of matter in terms of the arrangement, movement and energy of the particles

#1.2

understand the interconversions between the three states of matter in terms of:

  • the names of the interconversions
  • how they are achieved
  • the changes in arrangement, movement and energy of the particles.
#1.3

understand how the results of experiments involving the dilution of coloured solutions and diffusion of gases can be explained

#1.4

know what is meant by the terms:

  • solvent
  • solute
  • solution
  • saturated solution.
#1.5C

know what is meant by the term solubility in the units g per 100 g of solvent

#1.6C

understand how to plot and interpret solubility curves

#1.7C

practical: investigate the solubility of a solid in water at a specific temperature
