31. The modelling system is based on the conservation of mass and momentum in three dimensions of a Newtonian fluid. 32. J . Contreras ( 2010 ) developed a model for low amplitude detachments using the conservation of mass equation. 33. Lavoisier was the first to conclude by experiment that the Law of Conservation of Mass applied to chemical change. 34. The law of conservation of mass dictates that the quantity of each element does not change in a chemical reaction. 35. The book contains the results of numerous experiments and establishes an early version of the law of conservation of mass . 36. So while not strictly true, conservation of mass works for just about anything on the ordinary scale of things. 37. Conservation of mass applies here, so the particles that make it up will still be given tremendous kinetic energy.38. By conservation of mass , the mass of the ejected gas will be equal to the original mass of the propellant. 39. This is the conservation of mass -energy ( first law of thermodynamics ) contained within a part of the universe. 40. Letting g = m, the mass of the particle, the integrated Boltzmann equation becomes the conservation of mass equation:
