Question

what does the law of conservation of energy state

Answer 1

matter and energy cannot be created nor destroyed?

Answer 2

Total energy is conserved (which means it cannot be created or destroyed), but it can be converted from one form to another.

There are other statements of the law that allow for energy to be added to or lost from a particular volume of space, and tfor the addition or performance of work. Some apply to steady state flow situations.

My first statement should suffice.

Mass is a form of energy, and it can be converted to energy using the Einstein formula E = m c^2.
