EVERYDAY SCIENCE

Detailed explanation-1: -The law of conservation of mass states that matter cannot be created or destroyed in a chemical reaction. For example, when wood burns, the mass of the soot, ashes, and gases equals the original mass of the charcoal and the oxygen when it first reacted. So the mass of the product equals the mass of the reactant.

Detailed explanation-2: -The law of conservation of matter says that in chemical reactions, the total mass of the products must equal the total mass of the reactants.

Detailed explanation-3: -conservation law, also called law of conservation, in physics, a principle that states that a certain physical property (i.e., a measurable quantity) does not change in the course of time within an isolated physical system.

Detailed explanation-4: -When something burns up, the matter does not vanish. The materials simply turn into gases you cannot see. When you bake, food seems to magically get larger. Expanding air bubbles caused the baked treats to expand, but more matter was not formed. Candles change form when they are burned.
