\nThe statement that energy can neither be created nor destroyed is a fundamental principle known as the Law of Conservation of Energy (also the First Law of Thermodynamics). This law states that the total energy of an isolated system remains constant over time. Energy can be transformed from one form to another (e.g., potential energy to kinetic energy, chemical energy to heat and light), but the total amount of energy in the universe is conserved.

\n– Law of Conservation of Energy: Energy cannot be created or destroyed.
\n– Energy can be transformed between different forms.
\n– The total energy in a closed system remains constant.
\n<\/section>\n
\nIn the context of mass-energy equivalence (E=mc\u00b2), mass can be converted into energy and vice versa, for example, in nuclear reactions. However, this is still considered a transformation of mass into energy, not the creation or destruction of the fundamental entity of “mass-energy”. In many common physical and chemical processes, mass conservation and energy conservation can be treated separately.
