Matter – anything that has mass & volume.

Classification of Matter
Physical Property – a property that can be determined
without altering the chemical composition of the material (ex. colour, odour,
melting point)
Quantitative Property – a measurable property that has a
number and a unit (ex. density, mass)
Qualitative Property – simply a description that does not
have a measurement (ex. colour, odour)
Chemical Property – a property that describes how matter
behaves in the presence of other substances or when subjected to heat, light or
electricity (ex. iron reacts with oxygen to form rust)
Physical Change – a change in which the chemical
identity or composition of the sample of matter remains the same (ex. cutting
wood, all changes of state, dissolution)
Chemical Change – a change in which at least one new
substance is formed (ex. burning wood)
