검증된 단계별 안내1
Understand the Law of Conservation of Energy, which states that energy cannot be created or destroyed, only converted from one form to another.
Recognize that chemical reactions involve changes in energy, but the total energy remains constant; it is not lost but transformed.
Identify that kinetic energy is the energy of motion, not stored in chemical bonds; chemical bonds store potential energy.
Recall that potential energy is stored energy based on position or arrangement, such as in chemical bonds, not energy of motion.
Conclude that the true statement is that energy can be converted from one form to another but cannot be created or destroyed.
