Chemical Properties

Qualitative Property

A property that cannot be measured and is observed using your senses, such as colour or odour.

Quantitative Property

A property that is measurable and has a value, such as temperature, height, or mass.

Optical Clarity

How clear an object appears; categorized as transparent, translucent, or opaque.

Solubility

The ability of a substance to dissolve in another substance.

Malleability

The ability of a substance to be rolled or hammered into various shapes.

Ductility

The ability of a substance to be drawn into wires.

Viscosity

A measure of how much matter resists flow.

Electrical Conductivity

A measure of how well electric currents move through a substance.

Characteristic Physical Property

A physical property unique to a substance that can be used to identify it, such as density or boiling point.

Melting and Boiling Point of Water

Water melts/freezes at 0°C and boils at 100°C.

Density Formula

D = m / V (Density equals mass divided by volume).

Physical Change

A change in which the substance's composition remains the same and no new substances are produced.

Chemical Property

A description of what a substance does when it reacts to produce new substances, such as flammability or reactivity.

Chemical Change

A change that causes the identity of a substance to change, forming something new with new properties.

Evidence of a Chemical Change

Colour change, gas production, precipitate formation, energy change, and odour change.
