<P> The law of conservation of mass or principle of mass conservation states that for any system closed to all transfers of matter and energy , the mass of the system must remain constant over time , as system 's mass can not change , so quantity can not be added nor removed . Hence , the quantity of mass is conserved over time . </P>
