Question

A change in which no new substance is formed is known as ________.

Answer 1

Physical Change:

• When a substance undergoes a physical change, its composition remains the same despite its molecules being rearranged.
• Physical change can be reversible or irreversible.
• A physical change affects only physical properties i.e. shape, size, etc.
• A physical change involves very little to no absorption of energy.

Example: Freezing of water, melting of wax, etc.

Therefore, a change in which no new substance is formed is known as physical change.
