Exploring the principle of mass conservation in classical physics, this concept asserts that the mass of an isolated system remains constant over time, barring external forces. It underpins fluid dynamics and solid mechanics, and is crucial in chemistry for stoichiometry. Historical figures like Lomonosov and Lavoisier contributed to its development, while Einstein's relativity introduced mass-energy equivalence, expanding the principle to include energy conservation.
