Answer to Question #232985 in English for Manda

Question

Prove the conservation of matter experimentally

Answer 1

The amount of matter is conserved when a substance changes form. When matter changes drastically it is not actually destroyed. This can be tested by weighing all the materials involved in an experiment before starting it, and again after the experiment.

Lavoisier's experiments marked the first time someone clearly tested this idea of the conservation of matter by measuring the masses of materials both before and after they underwent a chemical reaction.
