Key Topics to Revise

1

Physical Properties of Water

  • Water is a colourless, tasteless, and odourless liquid.
  • It has no fixed shape—it takes the shape of its container.
  • Water exists in three states: solid (ice), liquid (water), and gas (steam or water vapour).
2

Water and Solutions

  • A solution is formed when a substance dissolves in water.
  • The substance that dissolves is called the solute (e.g., salt, sugar).
  • The liquid in which it dissolves is called the solvent (e.g., water).
3

Conditions Affecting Dissolving

  • More solvent helps dissolve solute faster.
  • Stirring speeds up dissolving.
  • Hot water dissolves sugar or salt faster than cold water.
4

Floating and Sinking

  • Objects lighter than water float (e.g., cork, plastic, wood).
  • Objects heavier than water sink (e.g., coin, key, stone).
  • Whether something floats or sinks depends on its weight compared to water.
