It is an observed fact of nature, known for at least a hundred years now. There are no known processes that can create energy where there was none before.
As to the reason, it is quite complicated. Basically, it is related to Nöther's Theorem. Every conservation law is related to a law of symmetry in nature. In the case of conservation of energy, it is related to the fact that the laws of nature don't change over time. In other words, if energy could be created or destroyed, then the laws of nature would be changing all the time! Please note that the math required to understand the details is quite complicated.
matter. In one of the sciency laws it clearly states that matter is neither created nor destroyed.
Energy can neither be created nor destroyed, but it can be made to change forms.
Renew itself or disappearEnergy can not be air.
The law of conservation of energy states that energy is neither created nor destroyed, but it can be transformed from one form to another.
The law of conservation of energy applies in physical sciences, and states that energy can neither be created nor destroyed.
Energy is neither created or destroyed.
Energy is cannot be created nor destroyed it can only be moved.
Energy is neither created nor destroid because energy is transfer from one form into another
No. The first law of thermodynamics states that energy may be neither created nor destroyed.
It means that energy can neither be created nor destroyed.
It means that energy can neither be created nor destroyed.
Yes, this is right.
In a closed system, energy can neither be created nor destroyed.
In a closed system, energy can neither be created nor destroyed.
matter. In one of the sciency laws it clearly states that matter is neither created nor destroyed.
a matter that cant be created or destroyed. it can change form but have a fixed volume.
When something is neither created nor destroyed, it is said to be a CONSERVED quantity.
