# Is the first law of thermodynamics another way of stating the law of conservation of energy?

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

it is known as 2 thing the first law of thermodynamics and the law of conservation of energy

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

That is known as the "Law of Conservation of Energy". It is also known as the "First Law of Thermodynamics".

The 1st Law of thermodynamics is a restatement of the law of conservation of energy.

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.

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").

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

The Second Law of Thermodynamics is equivalent to the Law of Conservation of Energy. The Law of Conservation of Matter is not stated in the laws of Thermodynamics.

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

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

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 the same as 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 Law of the Conservation of Energy. Stating it can be neither created or destroyed but changed from one form to another.

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