Question

स्टेट लॉ ऑफ कंजर्वेशन ऑफ मैटर​

Answer 1

Answer:

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

Explanation:

Formula

\frac{\partial\rho}{\partial t}+\nabla \cdot (\rho v)=0

\rho = density

t = time

\nabla = divergence

v = flow velocity field

The Law of Conservation of Mass dates from Antoine Lavoisier's 1789 discovery that mass is neither created nor destroyed in chemical reactions.
