Question

Prove the electric bell is ringing is physical change

Answer 1

Ringing of an electrical bell is a physical change because -

It only causes change in physical properties like the sound volume of the electrical bell.

No new chemical substance is formed by the ringing of an electric bell.
So it cannot be termed as a chemical change.

Heat is neither produced nor absorbed during the ringing of an electrical bulb, so it is called as a physical change.
