conservation of mass

n.
A principle in classical physics stating that the total mass of an isolated system is unchanged by interaction of its parts.

conservation of mass

n
(General Physics) the principle that the total mass of any isolated system is constant and is independent of any chemical and physical changes taking place within the system

n.
the principle that in a system not subject to any external force, the mass is constant despite its changes in form.
Also called conserva′tion of mat′ter.
