The Law of the Conservation of Energy States That

Question

The law of the conservation of energy states that
A) The total energy of the universe is constant
B) Entropy of a system increases
C) There are three laws of thermodynamics
D) The work that can be performed by a system is a constant
E) The energy of a system's surroundings is constant

Accepted Answer

The law of the conservation of energy, a fundamental concept in physics, states that the total energy of an isolated system remains constant—it is said to be conserved over time. Energy can neither be created nor destroyed; rather, it can only be transformed or transferred from one form to another. This principle is what choice A accurately reflects. Choices B and C refer to different aspects of thermodynamics, D and E are incorrect interpretations of energy principles.
