Question

select the correct answer. what does the law of conservation of energy state? a. energy can be created from nothing. b. energy cannot be destroyed. c. energy cannot change forms. d. the total amount of energy in a system changes continuously.

Explanation:

The law of conservation of energy states that energy cannot be created or destroyed, only transformed from one form to another.

• Option A is incorrect because energy cannot be created from nothing.
• Option B is correct as the law states energy cannot be destroyed (nor created, only transformed).
• Option C is incorrect because energy can change forms (e.g., potential to kinetic energy).
• Option D is incorrect because the total amount of energy in a closed system remains constant, not changes continuously.

Answer:

B. Energy cannot be destroyed.
