How do we have energy if it Cannot be created?

First Law of Thermodynamics: Energy can be changed from one form to another, but it cannot be created or destroyed. The First Law of Thermodynamics (Conservation) states that energy is always conserved, it cannot be created or destroyed. In essence, energy can be converted from one form into another.

Why energy Cannot be created destroyed?

Because energy is the movement state of mass, and the movement of mass cannot be created or destroyed. The movement state of mass just change from one form to another. A mass move due to it is the fundamental natural tendency for matter to stay at the thermodynamically more stable state at that moment.

Can energy be created or destroyed?

Conservation of energy is one such law. If energy could be created or destroyed, all of our ideas of how the world works would have to be modified in some way (and we’d learn something very perplexing). But so far, energy seems not to be created or destroyed.

Can energy be transformed from one form to another?

Although, it may be transformed from one form to another. If you take all forms of energy into account, the total energy of an isolated system always remains constant. All the forms of energy follow the law of conservation of energy. In brief, the law of conservation of energy states that

How do we get energy from food?

Mostly, we get it through the consumption of food, which gives us chemical energy. That chemical energy is then transformed into kinetic energy that is ultimately used to power our muscles. As we know through thermodynamics, energy cannot be created nor destroyed.

What happens to energy when matter changes state?

It simply changes states. The total amount of energy in an isolated system does not, cannot, change. And thanks to Einstein, we also know that matter and energy are two rungs on the same ladder.
