<u>Answer:</u> Yes, the mass will remain conserved during a physical change.
<u>Explanation:</u>
Law of conservation of mass states that mass can neither be created nor be destroyed, but it can only be transformed from one form to another form. In a reaction, total mass on the reactant side will always be equal to the total mass on the product side.
We are given:
Mass of water = 200 g
So, during a physical reaction of water, the mass will remain conserved.
Thus, the answer will be yes, the mass will remain conserved during a physical change.
