In general, if some quantity (in a closed system) doesn't change over time, it is said that there is a conservation law. In this case, what doesn't change is the total amount of energy, so this is the law of conservation of energy.

What is the priniciple that says energy cannot be created or destroyed?

The Principle of Conservation of Energy.


Which physical law states that energy cannot be destroyed?

That's the law of "Conservation of Energy". It also says that energy cannot be created.


What The law of conservation of energy says what about series current?

The Law of Conservation of Energy says, "Energy cannot be created or destroyed, but may change from one form to another."


Is energy created when atoms are destroyed in a chemical reaction?

Atoms are never created or destroyed in a chemical reaction. There are the same number of each type of atom both before and after a chemical reaction. Atoms are never created of destroyed; the molecules are just re-arranged in their bonding with each other.


Where do energy get there energy from?

The law of Conservation of energy says: Energy can not be created, nor destroyed.Well you could be meaning how something gets its energy. It is usually transferred from one object to the next; sense energy cannot be created or destroyed. So a shove or push would transfer energy or a type of heat can too. rubbing and touching are both ways to transfer energy.


What law says that energy cannot be created or destroyed only changed?

It is called the First Law of Thermodynamics, sometimes also called The Law of conservation of energy.


Why principle of conservation of kinetic energy is not conserved during inelastic collision?

There is no law of conservation of kinetic energy. The law of conservation of energy says that energy cannot be created or destroyed, although it can be converted to different forms of energy. In inelastic collisions, kinetic energy is often transformed to heat energy, potential energy, and perhaps sound energy


When energy changes form some energy is .?

no it says in the law of conservation of energy, energy can not be created or destroyed only changed, but you may loose energy as a different form but you wont gain any


Why let say if the forward reaction is exothermic does this mean that the backward reaction gives out or take in heat and why?

If the forward reaction is exothermic then the back reaction would be endothermic. This happens because it upholds the law of conservation of energy, which says that energy cannot be created or destroyed.


What law says in chemical change energy is neither created or destroyed?

Scientists call this law the law of conservation of matter


When energy changes form is some energy gained?

no it says in the law of conservation of energy, energy can not be created or destroyed only changed, but you may loose energy as a different form but you wont gain any


Can energy be destroyed when converting from one form of energy to another?

Hmmm. Where do you suppose you got those words ... "energy ... destroyed" ? Could it be from the conservation law that says that energy can't be created or destroyed ? Is there a reason that you can't accept that law as a law ? One more time, read our lips: Energy is never created or destroyed. When it's changed from one form to another, you can never avoid having some of it leak away and no longer be available to you. But it's not destroyed, and it's always pretty easy to understand where the missing energy went.
