Question

The universe’s total amount of energy does not ever change, but the amount of this energy that is available to do work varies tremendously. What statement best explains the changes in available energy?(1 point) Responses Energy transfer always occurs through heat. Energy transfer always occurs through heat. Energy constantly changes from one form to another. Energy constantly changes from one form to another. 100% of energy is always converted with perfect efficiency. 100% of energy is always converted with perfect efficiency. The only way to create energy is through nuclear reactions.

Answer 1

The statement that best explains the changes in available energy is: Energy constantly changes from one form to another.

This reflects the principle of energy conservation and transformation, where energy can move between different forms (like kinetic, potential, thermal, etc.) but the total amount remains constant, influencing how much is available to do work.
