Give an example of a scientific law.

• A. The Theory of Relativity.
• B. The Law of Conservation of Energy.
• C. The Scientific Method.
• D. The Gas Constant for Ideal Gases.

Answer: (B)

A scientific law is a concise statement that describes a universal observation about how nature behaves, usually expressed mathematically, and it describes what happens rather than why it happens. The Law of Conservation of Energy fits this well: in an isolated system, the total energy remains constant, even though energy can change form (kinetic, potential, thermal, chemical, etc.). This principle holds across countless experiments and systems, from mechanics to thermodynamics to electromagnetism, which is why it’s regarded as a fundamental law rather than a theory or a method. The Theory of Relativity, in contrast, is a comprehensive theoretical framework that explains how space, time, and energy interrelate and makes many predictions; it’s a theory, not a law. The Scientific Method is a procedure for conducting investigations, not a natural-law statement about how the world operates. The Gas Constant for Ideal Gases is a constant used in equations like PV = nRT; while important, it’s a parameter, not a universal descriptive statement about nature, so it isn’t a law.
