Interpretation::
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.

Explain.arrow_forward
- What is Homogeneous substance? Give an example?arrow_forwardGive two chief characteristics of (i) Elements, (ii) Compounds and (ii) Homogeneous Mixtures.arrow_forwardI would say that the bubbles in boiling water are air and water vapor, being that boiling water should be a physical change, not a chemical one. Is that a correct conclusion?arrow_forward
