The statement "Energy constantly changes from one form to another" best explains the changes in available energy.
The statement that best explains the changes in available energy is: "Energy constantly changes from one form to another."
Explanation:
According to the first law of thermodynamics, also known as the law of conservation of energy, the total amount of energy in the universe remains constant. However, this energy can change between different forms such as heat, light, electrical, chemical, or mechanical energy.
For example, when a car burns fuel, chemical energy is converted into thermal energy, which is then used to do work and move the car. This is an example of the transformation of energy from one form to another.
Therefore, the available energy for doing work can vary tremendously based on the efficiency of the energy transfer and the conversion between different forms of energy. It is important to note that energy transfer does not always occur through heat; it can occur through various other mechanisms depending on the specific system or process involved.
