lavoisier law of conservation of matter

Stated by French chemist A. Lavoisier "During any physical or chemical change, the total mass of the products remains equal to the total mass of the reactants". Law of conservation is also known as 'Law of indestructibility of matter..

A.L.Lavoisier and P.S.Laplace gave this law in 1780 which states that 'the enthalpy of a reaction is exactly equal but opposite in sign for the reverse reaction'. For example, if D H is the enthalpy change in going from A to B then the enthalpy change for the process B to A wo..

Summary Matter - anything which has mass, occupies space and can be perceived by our senses. Law of conservation of matter - matter can neither be created nor destroyed. The states of matter are solid, liquid gas, plasma and sup..

The total energy in the universe is present either as kinetic energy or as potential energy. For example, the water stored in a dam possesses potential energy by virtue of its height (position). When this water is allowed to fall, its potential energy gets converted into kinetic energy. Falling wat..

Law of conservation of energy states that the energy can neither be created nor destroyed but can be transformed from one form to anothe..

It is a common experience that energy cannot be generated without consuming energy of some other kind. If a certain amount of one kind of energy is produced, an equal amount of some other kind of energy disappears so that the total energy of the Universe remains constant. This observation forms the..
