Which of these is an example of a physical change? a) iron melting b) steel rusting c) paper burning d) wood decaying

Option (A) is the correct answer.

Explanation:

A change in chemical reaction which results in the formation of new compounds is known as a chemical change whereas a chemical reaction in which there is no formation of any new compounds is known as a physical change.

For example, rusting of iron is a chemical change and melting of ice is a physical change.

Therefore, out of the given options iron melting is a physical change because melting causes change in intermolecular forces and no formation of any new products.

Thus, iron melting is a physical change.
