Qualitative and Quantitative Physical Properties of Matter

Physical Properties Are characteristics of a substance that can be observed and measured without changing the identity of the substance Physical Properties Qualitative vs Quantitative

Qualitative Physical Properties Qualitative properties of a substance can be observed through the senses: sight, sound taste, smell, touch What are some examples?

Examples of Qualitative Properties State Clarity Colour Odour Homogeneity Taste Texture Lustre Ductility Malleability Brittleness

Sodium Metal

Copper Metal

Quantitative Physical Properties Can be measured and assigned a particular value They are often unique to a particular element or compound Recorded values are available for reference (can look it up)

Examples of Quantitative Properties Have a numerical value Melting point Boiling point Density conductivity Solubility Viscosity Hardness

Chemical Properties

Chemical Property Chemical properties of matter are those that relate to how the substance changes in composition or how it interacts with other substances. Reaction with water Reaction with acid Combustibility Reactivity /Explosive Corrosion (rust, tarnish)
