Law of Conservation of Energy and Mass
The law of conservation of energy, a fundamental concept of physics, states that the total amount of energy remains constant in an isolated system. It implies that energy can neither be created nor destroyed, but can be change from one form to another. The law of conservation of mass states that the total amount of mass remains constant in an isolated system in spite of any physical or chemical changes that may take place.

Conservation of Matter Grade: 5 - 12 When matter changes phases, does any matter appear or disappear? Learn about the law of conservation of matter. 5:50 |
Law of Conservation of Mass Grade: 5 - 12 The lesson explains the law of conservation of mass. 4:35 |
Chemistry Concepts: Conservation of Mass Grade: 5 - 12 The presentation illustrates the concept of conservation of mass and energy. When compounds react, no atoms are created or destroyed. So, the end products must weigh the same as the initial reactants. This is why the chemical equations need to be balanced. 1:05 |
