Question

select all the items that describe a part of the law of conservation of energy.
energy is not created. the amount of energy available in a system does not change.
energy transforms from one type to another. energy is not destroyed.
energy is always lost and cant be recovered. energy can be created from nothing.

Explanation:

The Law of Conservation of Energy states that energy is neither created nor destroyed. It can transform from one form to another, and the total energy in a system remains constant. The statements "Energy is not created", "The amount of energy available in a system does not change", "Energy transforms from one type to another", and "Energy is not destroyed" align with this law. The statements "Energy is always lost and can't be recovered" (energy isn't lost in the sense of disappearance, it just transforms, often to less - useful forms like heat) and "Energy can be created from nothing" (contradicts the law) are incorrect.

Answer:

Energy is not created, The amount of energy available in a system does not change, Energy transforms from one type to another, Energy is not destroyed.
