Question

Which statement is correct about the law of conservation of energy

Energy is created when water freezes.

Energy is destroyed when sugar is burned.

Energy stays inside molecules permanently.

Energy is transferred when atoms are rearranged

Answer 1

The law of conservation of energy states that energy is transferred when atoms are rearranged. Energy can be converted from one form to another, but the total amount of energy remains constant before and after a change.

Step-by-step explanation:

The correct statement about the law of conservation of energy is that energy is transferred when atoms are rearranged. According to the law of conservation of energy, energy can be converted from one form to another, but the total amount of energy present before and after a change remains constant. In chemical or physical changes, energy is neither created nor destroyed, although it can be changed in form. For example, when molecules rearrange during a chemical reaction, energy is transferred in the process.

Answer 2

The law of conservation of energy is energy isn't created or destroyed

A and B are wrong because there is creation or destruction of energy

C is wrong because energy can be transferred (think touching a hot stove with your finger. heat is transferred from the stove to your finger OUCH!)

D is correct because the energy is still there, but in a different form
