Classification of Matter
Physical Property
A physical property is a property that can be determined without altering the chemical composition of the material (ex. colour, odour, melting point).
Quantitative Physical Property
A quantitative physical property is a measurable property that has a number and a unit (ex. density, mass).
Qualitative Physical Property
A qualitative physical property is simply a description that does not have a measurement (ex. colour, odour).
Chemical Property
A chemical property is 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 physical change is 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 chemical change is a change in which at least one new substance is formed (ex. burning wood).
