Question

Which property of physical changes explains why matter is conserved in a physical change?

Answer 1

Yes, mass is conserved weather matter undergoes a chemical change or a physical change. physical change are changes that involve a simply change in phase. Condensing of a gas is an example. any change that does not involve a change in chemical composition is physical change........

Hope it's help you............

Answer 2

It takes place due to change in parameters

It is reversible.

Hence the matter is conserved.
