  • Change of state in matter using the Kinetic theory:
    • Boiling
    • Vaporization
    • Melting
    • Fusion
    • Evaporation
    • Condensation
    • Sublimation
    • Deposition
    • Freezing
  • Change of state diagrams (using the terms mentioned above).

Theme 2: Physical Quantities and Measurement

  • Measurement of Density of irregular solids using:
    • Eureka Can
    • Measuring Cylinder
  • Measurement of Density of Fluids:
    • Basic Concept
    • Concept of Floatation and sinking of a substance (relate to density)
    • Comparison of densities in the three states of matter.

Theme 3: Force and Pressure

  • Pressure:
    • Definition
    • Unit
    • Calculation of pressure in simple cases
    • Pressure exerted by liquids (Qualitative only).
    • Pressure exerted by gases - Atmospheric pressure (Qualitative only).
