# How is the first law of thermodynamics related to the law of conservation of energy?

The first law of thermodynamics is the law of conservation of energy. They are the same thing.

The first law of thermodynamics states that the energy within a closed system is constant regardless of changes in that system. The law of conservation of mass and energy states that total mass and energy (in a closed system) will always remain the same despite changes inside of the system.

The First Law of Thermodynamics is the Law of Conservation of Energy. Just different names for the same thing.

As stated by the expert: The First Law of Thermodynamics IS the Law of Conservation of Energy. The Second Law of Thermodynamics is not directly related; however, it provides additional restrictions, as to what can, and what cannot, be achieved.

That's related to the First Law of Thermodynamics - the Law of Conservation of Energy.

That would be the First Law of Thermodynamics. It is the same as Conservation of Energy.

The First Law of Thermodynamics is another name for the Law of Conservation of Energy.

The First Law of Thermodynamics is the conservation of energy. You can't create energy, nor destroy it; the total amount of energy in a closed system remains constant.The First Law of Thermodynamics is the conservation of energy.

No, the Law of Conservation of Energy (a.k.a. First Law of Thermodynamics) states that energy CAN NOT be created or destroyed. Converting energy to a less valuable form is related to the Second Law of Thermodynamics.

The First Law of Thermodynamics is the Law of Conservation of Energy. There is a quantity, called energy, which does not change (in a closed system). There are several types of energy, and it is possible to convert from one type of energy to another; but never will the total energy change.

The first law is about conservation of energy, the second is about the conservation of entropy.

Yes - the 1st law of thermodynamics is often referred to as "the law of conservation of energy". They are the same thing.

That's the same as the Law of Conservation of Energy.

Not exactly. The first law of thermodynamics, i.e. the law of conservation of energy, also accounts for heat as one of the many forms that energy can take. There is no one law called "the law of thermodynamics", but there are several "Laws of Thermodynamics" (note the plural form "LAWS").

Energy can't be created or destroyed. The First Law of Thermodynamics is also known as the Law of Conservation of Energy.

The First Law of Thermodynamics is the Law of Conservation of Energy - in other words, the total amount of energy in a closed system remains constant.

The First Law of Thermodynamics is a restatement of the Principle or Law of Conservation of Energy.

It is called precisely what you wrote in the title: "Law of Conservation of Energy". An alternative name is the "First Law of Thermodynamics".

Conservation of energy is found in energy efficient appliances.

It always applies. There are no known processes in which the Law of Conservation of Energy (i.e., the First Law of Thermodynamics) doesn't apply.

The first law is also known as law of conservation of energy. It say that the energy can neither be created nor be destroyed but can only be transferred. Its is given by this equation dQ = dU + dW .
