Is mass conserved when 200 g of water undergoes a physical change? Use complete sentences to support your answer by explaining how this can be demonstrated.

According to the law of conservation of mass, the mass of reactants will be equal to the mass of the products. The mass of products and reactants will only differ during a nuckear reaction

Changing of the physical state of water is not a nuclear reaction. So because of that the mass will remain constant without any change.

Hope this helps you!
