## What did Einstein mean when he said energy Cannot be created nor destroyed only transformed?

The law of conservation of energy states that energy can neither be created nor destroyed – only converted from one form of energy to another. This means that a system always has the same amount of energy, unless it’s added from the outside.

When did Einstein say energy Cannot be created or destroyed?

energy is neither created nor destroyed. In 1907 (I think), Albert Einstein announced his discovery of the equation E = mc2 and, as a consequence, the two laws above were merged into the Law of Conservation of Mass-Energy: the total amount of mass and energy in the universe is constant.

Why can’t matter be created or destroyed?

Matter is anything that has mass and takes up space. Matter can change form through physical and chemical changes, but through any of these changes, matter is conserved. The same amount of matter exists before and after the change—none is created or destroyed. This concept is called the Law of Conservation of Mass.

### How does energy exist if it Cannot be created?

The first law of thermodynamics, also known as Law of Conservation of Energy, states that energy can neither be created nor destroyed; energy can only be transferred or changed from one form to another. For example, turning on a light would seem to produce energy; however, it is electrical energy that is converted.

What is the idea that energy Cannot be created or 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.

Who first said energy Cannot be destroyed?

This law, first proposed and tested by Émilie du Châtelet, means that energy can neither be created nor destroyed; rather, it can only be transformed or transferred from one form to another.

#### Who said matter Cannot be created or destroyed?

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.

Which law energy Cannot be created or destroyed?

The law of conservation of energy
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.

## Can work be created or destroyed?

Laws of Thermodynamics | Back to Top Energy is the ability to bring about change or to do work. Thermodynamics is the study of energy. First Law of Thermodynamics: Energy can be changed from one form to another, but it cannot be created or destroyed.
