# Who stated the Law of conservation of mass?

Antoine Laurent Lavoisier stated the law of conservation of mass.

## Law of Conservation of Mass

The law of conservation of mass states that the mass in an isolated system can neither be created nor be destroyed but can be transformed from one form to another.

Law of conservation of mass can be represented in the differential form using the continuity equation in fluid mechanics and continuum mechanics as:

 $$\frac{\partial \rho }{\partial t}+\bigtriangledown (\rho v)=0$$

Where,

• $$ρ$$ is the density
• $$t$$ is the time
• $$v$$ is the velocity
• $$\bigtriangledown$$ is the divergence
