It is not possible to create matter out of nothing and hence the sum total of matter in the universe remains the same (similar to law of conservation of mass ).
Continuity equation main Regardless of the flow assumptions, a statement of the conservation of mass is generally necessary.
The conservation of mass flow rate leads one to expect that contracting the flow channel would increase the flow speed (i.e. making the channel narrower results in faster air flow) and at subsonic speeds this holds true.
The conservation of mass holds even as some types of particles are converted to others.
