[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.
