Water is found throughout the earth. It is comprised of hydrogen and oxygen atoms. Water changes into different physical states
without losing basic elemental structure. Using the law of the conservation of matter, explain how water changes phases and how water obeys this law. Write your evaluation in standard paragraph format with four or
five complete sentences.
Water obeys the Law of Conservation of Matter despite changing into different forms because when water does change forms, the amount of water stays the same. The Law of Conservation of Matter states that before matter undergoes change, be it through physical or chemical means, the same amount of matter exists. Matter cannot be created nor destroyed during the change. When water changes from a liquid to a gas the molecules change form by breaking the bonds that held them in a liquid state, but this does not create new matter. The molecules can now move more freely but are still the same as they were before. Same goes with the change from a liquid to a solid. The molecules slow down and become more compact, forming a solid. Though again, this does not create new matter nor destroy existing matter, therefore obeying the Law of Conservation of Matter.
