Question

Give an example to show law of conservation of mass applies to physical change also.

Answer 1

you can take balance weighing machine which is gud example for this

Answer 2

Law of conservation of mass states that mass can neither be created nor destroyed in a chemical reaction. However, this law applies to physical changes also. For example, when ice melts into water, the mass of ice equals to the mass of water, i.e., the mass is conserved. This verifies the law of conservation of mass.
