Question

does the law of conservation of mass hold good for physical changes also? Give an example to prove it.

​

Answer 1

Answer:

All chemical reactions are chemical changes. The Law of Conservation of Matter states that matter cannot be created or destroyed. In a physical change, substances can change form, but the total mass remains the same. In a chemical change, the total mass of the reactants always equals the total mass of the products.

For example, when ice melts into water, the mass of ice equals to the mass of water, i.e., the mass is conserved.
