Answer 1

Answer:

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 the system's mass cannot change, so quantity can neither be added nor be removed.

Answer 2

Answer:

${\huge{ \underline{ \sf{ \underline{☃Mass \: of \: conservation ☃}}}}}$

The Mass of conservation 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 cannot change, so quantity cannot be added nor removed. Hence, the quantity of mass is conserved over time.
