It is the Law of Conservation of Energy, aka the First Law of Thermodynamics.
The concept of energy is one of the most fundamental concepts of science.
This is the first law of thermodynamics and it is worth saying in several ways.
(A) Energy is conserved.
(That is short and accurate answer but non-scientists are not used to the word "conserved" being used in this way. But, scientists use it to mean "Stays the same" all the time.)
(B) Energy can change from one form of energy to another, but energy can not be created or destroyed.
(This is a fundamental law of Nature and the first law of thermodynamics, that energy of a closed system can never change. Sometimes it is said that "the total energy of the universe is always the same." )
Discussion:
Nature provides us with the Law of Conservation of Energy, whichever way you want to say it. It was about 400 years ago that science started to understand energy. At first it was only kinetic energy, the energy of motion, that was observed unchanged.
Soon this was expanded to include gravitational potential energy. Later this expanded to other forms such as elastic potential energy, heat energy, chemical energy, nuclear energy, electrical and many other forms, including the famous "mass energy," E=mc2.
How grand to know that the first law of thermodynamics says that we will never run out of energy. Alas, the second law says that Entropy is the problem and energy cannot always be used to do work.
Aside: There is a big discussion in cosmology now about "dark energy." This should not be confused with the possibility that maybe energy is not conserved. The truth is that cosmologists have no idea what this "dark energy" is and it is not even a sure thing that it is energy.)
No, the law of conservation of mass states that mass is neither created nor destroyed in a chemical reaction. However, the law of conservation of energy states that energy cannot be created or destroyed, only converted from one form to another.
The first law of thermodynamics states that energy cannot be created or destroyed in an isolated system; it can only change forms. This law is also known as the Law of Conservation of Energy.
Energy cannot be destroyed according to the law of conservation of energy, which states that energy can neither be created nor destroyed, but it can only be transformed from one form to another. This means that energy can change from one type to another, but the total amount of energy remains constant in a closed system.
energy cannot be created nor destroyed it can only change from one energy into another and this law is known as the: CONSERVATION OF ENERGY
The law that states energy cannot be created or destroyed is the First Law of Thermodynamics. It is also known as the law of energy conservation, which means that in a closed system, energy can only change forms but the total amount of energy remains constant.
No, the law of conservation of mass states that mass is neither created nor destroyed in a chemical reaction. However, the law of conservation of energy states that energy cannot be created or destroyed, only converted from one form to another.
The first law of thermodynamics states that energy cannot be created or destroyed in an isolated system; it can only change forms. This law is also known as the Law of Conservation of Energy.
the conservation of energy
Energy cannot be destroyed according to the law of conservation of energy, which states that energy can neither be created nor destroyed, but it can only be transformed from one form to another. This means that energy can change from one type to another, but the total amount of energy remains constant in a closed system.
No. The first law of thermodynamics states that energy may be neither created nor destroyed.
energy cannot be created nor destroyed it can only change from one energy into another and this law is known as the: CONSERVATION OF ENERGY
The law that states energy cannot be created or destroyed is the First Law of Thermodynamics. It is also known as the law of energy conservation, which means that in a closed system, energy can only change forms but the total amount of energy remains constant.
[the law of conservation of energy]Wrong: The law of conservation of energy says that energycannot be created or destroyed. Do not change an answer unless you know the answer.The correct answer is the Law of Conservation of Charge, which states that the net charge of an isolated system remains constant.
The law that states energy is never created or destroyed is the First Law of Thermodynamics, also known as the Law of Conservation of Energy. This law states that energy can be transferred or transformed, but it cannot be created or destroyed.
The law that states energy cannot be created or destroyed is the First Law of Thermodynamics, also known as the Law of Conservation of Energy. This law states that energy can only change forms or be transferred from one object to another, but the total amount of energy in a closed system remains constant.
C. Energy can be created but not destroyed. This statement aligns with the law of conservation of energy, which states that energy cannot be created or destroyed, only converted from one form to another.
This is known as the law of conservation of energy, a fundamental principle in physics. It states that the total energy of an isolated system remains constant over time; it can change forms but cannot be created or destroyed.
