Which law states: "energy cannot be created or destroyed"?
A
First Law of Thermodynamics
B
Law of Conservation of Mass
C
Second Law of Thermodynamics
D
Third Law of Thermodynamics
Verified step by step guidance1
Understand that the question is asking about a fundamental principle related to energy in chemistry and physics.
Recall that the statement "energy cannot be created or destroyed" refers to the conservation of energy within a system.
Identify that this principle is formally known as the First Law of Thermodynamics, which is a version of the Law of Conservation of Energy.
Note that the Law of Conservation of Mass deals with matter, not energy, so it is not the correct choice here.
Recognize that the Second and Third Laws of Thermodynamics address entropy and absolute zero temperature, respectively, and do not state the conservation of energy.
