Question

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

Answer 1

Yes, mass is conserved when 200 g of water undergoes a physical change. This can be demonstrated through the law of conservation of mass, which states that mass cannot be created or destroyed, only transformed into different forms. In this case, when water undergoes a physical change, such as melting or boiling, its physical state changes, but its mass remains the same. So, if we measure the mass of the water before and after the physical change, we will find that it will still be 200 g, thus demonstrating the conservation of mass.
