Question

state and explain the law of conservation of energy and the law of conservation of mass with examples.​

Answer 1

◼ Law of conservation of energy :-

↠ The law of conservation of energy states that energy cannot be created or destroyed. It can only be changed from one form to another.

↠ A system always has the same amount of energy, unless it is added from outside

◼ Law of conservation of mass :-

↠ The law of conservation of mass states that mass, in an isolated system, can neither be created nor destroyed by chemical reactions.

↠ The mass of the products in a chemical reaction is equal to the mass of the reactants.
