Examples of physical properties: state of matter (solid, liquid or gas), melting point, boiling point, density, colour, solubility, mass, volume, concentration, electrical conductivity, thermal conductivity…

 

Chemical property refers to the characteristic of matter which enables it to change its chemical composition.

Examples of chemical properties: reactivity with chemicals (such as oxygen, water, hydrogen etc.), flammability, electronegativity…
