Energy can not be created or destroyed, but transferred and transformed into other forms of energy is stated in…
A The Law of Conservation of Matter
B The Law of Conservation of Energy
C The Law of Energy and Motion
D The Law of Thermodynamics
The correct answer and explanation is:
The correct answer is B: The Law of Conservation of Energy.
The Law of Conservation of Energy states that energy can neither be created nor destroyed. It can only be transferred from one form to another. This principle is fundamental in physics and applies across all types of systems, from mechanical to thermal, and even chemical processes. For example, when a moving car brakes, the kinetic energy (energy of motion) is converted into heat energy due to friction between the brake pads and the wheels. This energy is not lost but transformed into a different form, which is why the total amount of energy in the system remains constant.
This law is one of the cornerstones of thermodynamics and explains many natural processes. For instance, in a power plant, chemical energy from fossil fuels is converted into thermal energy through combustion. The thermal energy is then converted into mechanical energy by turbines, which ultimately generates electrical energy for use. Despite all these conversions, the total amount of energy in the system is conserved; it simply changes form.
In contrast, the Law of Conservation of Matter (Answer A) states that matter cannot be created or destroyed, which is a separate principle from energy conservation. Answer C, “The Law of Energy and Motion,” is not a standard term in physics. Answer D, “The Law of Thermodynamics,” refers to a broader set of principles governing energy and its transformations, of which the Law of Conservation of Energy is a part.
This conservation principle helps engineers, scientists, and other professionals calculate energy changes and design systems that manage energy efficiently.
