Based on the Law of Conservation of Energy, the correct answer is:
Energy cannot be created or destroyed by ordinary chemical or physical means.
To understand why this is true, we first need to understand the Law of Conservation of Energy. This law states that the total amount of energy in a closed system remains constant over time.
To arrive at this answer, we can first eliminate the options that involve the relationship between kinetic energy and potential energy minus temperature. Both of these options are not accurate representations of the Law of Conservation of Energy.
Next, we can eliminate the option that states kinetic energy is always equal to potential energy. While kinetic energy and potential energy can be equal in certain situations, they can also be different. For example, an object at rest has potential energy due to its position, but zero kinetic energy. Conversely, an object in motion has kinetic energy but may have zero potential energy if it is at a fixed height.
This leaves us with the final option: Energy cannot be created or destroyed by ordinary chemical or physical means. This statement aligns with the Law of Conservation of Energy, which states that energy is conserved within a closed system. Energy can be converted from one form to another, such as potential energy being converted into kinetic energy or thermal energy, but the total energy within the system remains constant.
Therefore, the correct answer is that energy cannot be created or destroyed by ordinary chemical or physical means.
