conservation

The law of conservation of charge is a fundamental principle in physics that states the total electric charge in an isolated system remains constant over time. This law is based on the observation that electric charge can be neither created nor destroyed, only transferred between objects. The unit for measuring electric charge is the coulomb … Read more

The law of conservation of matter, also known as the principle of mass conservation, is a fundamental principle in physics and chemistry that states that matter can neither be created nor destroyed, but can only be transformed from one form to another. This principle is based on the observation that the total mass of a … Read more
