What principle states that energy can neither be created nor destroyed?

• A. Energy Preservation Principle
• B. Law of Conservation of Energy
• C. 1st Law of Thermodynamics
• D. Energy Equilibrium Law

Answer: (C)

The principle that states energy can neither be created nor destroyed is indeed known as the Law of Conservation of Energy. This fundamental concept from physics reflects the idea that the total energy of an isolated system remains constant, meaning energy can only change forms—for example, from kinetic to potential energy—but the total amount of energy stays the same.

This principle is foundational not only in physics but also in various fields including chemistry and environmental science, as it underlines many processes, such as energy generation and consumption cycles. The application of this law is crucial in understanding various energy systems and the impact of human activities on the environment.

While the first law of thermodynamics also describes this principle, mentioning it does not encapsulate the broader implications and context that the Law of Conservation of Energy conveys. Therefore, this law is often referenced in discussions of energy efficiency, sustainability, and resource management, which relate closely to environmental awareness.
