Question

question 7 (3 points) states that in all physical or chemical changes, energy is neither created nor destroyed, but it may be converted from one form to another. a) the potential energy b) the first law of thermodynamics c) the second law of thermodynamics d) all of the above

Explanation:

The first law of thermodynamics, also known as the law of conservation of energy, states that energy can neither be created nor destroyed in an isolated system; it can only be transformed from one form to another. Potential energy is a form of energy, not a law. The second law of thermodynamics is about entropy and the direction of natural processes (e.g., heat flows from hot to cold spontaneously). Since only the first law matches the given description, options a, c, and d are incorrect.

Answer:

B. The first law of thermodynamics
