释义
Lavoisier, Antoine Laurent (1743–94)

Physics
  • who collected taxes for the government in Paris. In the 1770s he discovered oxygen and nitrogen in air and demolished the phlogiston theory of combustion by demonstrating the role of oxygen in the process. In 1783 he made water by burning hydrogen in oxygen (see Cavendish, Henry). He also devised a rational nomenclature for chemical compounds. In 1794 he was tried by the Jacobins as an opponent of the Revolution (because of his tax-gathering), found guilty, and guillotined.


Chemical Engineering
  • A French chemist noted for determining the components of water as being oxygen and hydrogen, and establishing that sulphur is not a compound but an element. He also helped to formulate the metric system. Through very careful experimentation he was the first to show that although matter can change its state in a chemical reaction, the total mass remains the same at the end as at the beginning of every chemical change. He was the first to state the conservation of mass. During the French Revolution, he was accused of various crimes and guillotined.
