[Science Form 1] Physical Appearance & Behaviour

A property describe the physical appearance and behaviour of an object.

Some properties of matter include: size, shape, colour, texture, reactivity, melting point and boiling point.

Below are the physical properties of each state of matter.

Solid
  • Shape: Fixed/definite.
  • Volume: Fixed/definite.
  • Density: High.
  • Compressibility: Not easily compressible.

Liquid
  • Shape: Indefinite (liquids take the shape of the part of the containers they occupy).
  • Volume: Fixed/definite.
  • Density: High.
  • Compressibility: Not easily compressible.

Gas
  • Shape: Indefinite (gases take the shape of their container).
  • Volume: Indefinite (gases take the volume of their containers).
  • Density: Low.
  • Compressibility: Easily compressible.
