Best answer

Conservation of Energy and Mass The law of conservation of mass states that in achemical reaction mass is neither created nor destroyed. For example, the carbon atom in coal becomes carbon dioxide when it is burned.

  • What is the law of Conservation of mass and energy?

  • The Law of conservation of energy is similar to that of the Law of conservation of mass. According to the Law of conservation of energy, the total energy of a closed system (a system isolated from its surroundings) is conserved. This means energy can neither be created nor be destroyed.

  • How was mass conserved in chemistry?

  • The conservation of mass dates back to the late 1700s with Antonie Lavoisier’s chemistry experiments. He showed that mass is conserved in a chemical reaction. The conservation of energy was discovered in the mid-1800s by Julius Robert Mayer, who was a surgeon who treated people by blood-letting.

  • What is the conservation of mass-energy?

  • The delicate measurements by Etvs and later workers ( see鈥?鈥as alternatively been named the conservation of mass-energy or the conservation of total energy.

  • What is the conservation of mass energy in nuclear reactions?

  • Generally, in both chemical and nuclear reactions, some conversion between rest mass and energy occurs so that the products generally have smaller or greater mass than the reactants. Therefore the new conservation principle is the conservation of mass energy. See also: Energy Release from Fission.
