Question

Based on the law of conservation of energy, which statement is correct?

A.Energy is always being added to all parts of the universe.
B. Energy is often destroyed in some parts of the Universe.
C.Energy is a closed system cannot change forms.
D.Energy in an isolated system remains constant.

Answer 1

D. Energy is an isolated system that remains constant.

Step-by-step explanation:

The law of conservation of energy states that the amount of energy is neither created nor destroyed, (but can be only changed from one form into another or transferred from one object to another).For example, when you play the piano and hit the keys, the energy of the person who plays the piano, will be transferred to the keys of the piano.

• According to the law of conservation whenever a form of energy transforms and changes to another, the total amount of energy remains constant,

the answer towards your question shall be D. is the correct statement.
