Which of the following statements refer/s to the law of conservation of energy? Statements: I) Energy can be converted from one form to another form of energy. II) Energy can neither be created nor destroyed.
Both Statements I and II
The correct answer is option 1 I.e. Both statement I and II.
Both statements I and II refer to the law of conservation of energy.
Statement I is correct: Energy can change from one form to another (e.g., potential to kinetic, electrical to thermal).
Statement II is also correct: Energy cannot be created or destroyed; the total energy in a closed system remains constant.
