Question

Why is melting of wax a physical change?

Answer 1

Physical change:

• Physical change is a type of change in which the chemical composition of the substance remains the same.
• The melting of wax is a simple conversion of state from solid to liquid without any chemical change, hence melting is a physical change.
• It is a reversible reaction, and the original substance can be brought back by reversing the process.
• Another example of physical change is: Melting of ice, and evaporation of water.
