: To determine solutions of potassium chromate are bright yellow coloured is an example of a physical property or chemical property. Concept Introduction: In the physical change, the material or substance will not change its chemical identity only changes its physical state like solid into liquid or liquid into gas. For example, water changes its physical sate when ice melts into water. In the chemical change, the material or substance will change its chemical identity means there is a new substance formed by the formation heat, energy or gas. For example: hydrogen and oxygen react to form water which is a new substance.

Air consists of mainly N₂ and O2, plus CO2 and other impurities. Air is classified as
a pure element
a homogeneous mixture
a heterogeneous mixture
an impure element
a compound
Using examples, explain the difference between a physicalproperty and a chemical property.
114. Classify each as a pure substance or a mixture. If it is a pure
substance, classify it as an element or a compound. If it is a
mixture, classify it as homogeneous or heterogeneous.
