Question

Q7. Give an example to show that law of conservation of mass applies to
physical changes also​

Answer 1

Answer:

I think this is correct

Explanation:

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

Answer 2

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

Answer:
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.
