# What is the definition of law of conservation of matter

## What is the meaning of law of conservation of matter?

the principle that in any closed system subjected to no external forces, the mass is constant irrespective of its changes in form; the principle that matter cannot be created or destroyed.

## Who explained the law of conservation of matter?

Antoine LavoisierA portrait of Antoine Lavoisier, the scientist credited with the discovery of the law of conservation of mass. This law states that, despite chemical reactions or physical transformations, mass is conserved — that is, it cannot be created or destroyed — within an isolated system.

## What does law say about matter?

Another way of stating this is, “In a chemical reaction, matter is neither created nor destroyed.” The law of conservation of mass is also known as the “law of indestructibility of matter.”5 дней назад

## What is law of conservation of matter and energy?

The law of conservation of matter and energy states that matter is neither created nor destroyed but conserved. Humans do not have the ability to create or destroy matter (atoms) or energy. They can only rearrange the matter and energy. For example, an oxygen atom will cycle through a living system.

## What is the law of conservation of matter for Kids?

The law of conservation of mass is a fundamental principle of physics. According to this law, matter can be neither created nor destroyed. In other words, the mass of an object or collection of objects never changes, no matter how the parts are rearranged.

## What are the 3 basic laws of matter?

Laws of Chemistry

The law of the conservation of mass. The law of constant proportions. The law of multiple proportions. The law of reciprocal proportions.

## Can matter be created?

The first law of thermodynamics doesn’t actually specify that matter can neither be created nor destroyed, but instead that the total amount of energy in a closed system cannot be created nor destroyed (though it can be changed from one form to another).

## Can atoms be destroyed?

All matter is composed of extremely small particles called atoms. Atoms of a given element are identical in size, mass, and other properties. Atoms of different elements differ in size, mass, and other properties. Atoms cannot be subdivided, created, or destroyed.

## Does the law of conservation apply to physical changes?

The Law of Conservation of Matter states that matter cannot be created or destroyed. In a physical change, substances can change form, but the total mass remains the same. In a chemical change, the total mass of the reactants always equals the total mass of the products.

## Can neither be created nor destroyed?

The law of conservation of energy, also known as the first law of thermodynamics, states that the energy of a closed system must remain constant—it can neither increase nor decrease without interference from outside. … The sum of these is called mechanical energy.

## Is it possible to destroy matter?

Matter can neither be created nor destroyed. This is the law of conservation of matter (mass). … The amount of water (matter) stayed the same, but the volume just changed a bit. We are really using the Law of Conservation of Mass-Energy.

## What is the concept of conservation of energy?

Energy may be converted from one form to another. The principle of conservation of energy states that the total amount of energy remains the same in such conversions, i.e. energy cannot be created or destroyed.
