The first law of thermodynamics is the law of conservation of energy. Energy cannot be created nor destroyed, but only changed in form.
For example when water turns a turbine in a hydroelectric power station. the loss in kinetic energy of the water is equivalent to the electric energy produced plus the waste heat, sound etc.
Let a system absorbs Q amount of heat energy from the external source. As a result of this, let W be the work done by the system on its surrounding and ΔU be the change in the internal energy of the system. According to the law of conservation of energy,
Q = ΔU + W
which is the mathematical statement of the first law of thermodynamics.
Thus, the first law of thermodynamics may be stated as:
The energy entering the system in the form of heat is equal to the sum of the increase in the internal energy of the system and the energy leaving the system in the form of work done by the system on its surroundings.
What else can I help you with?
Which law of science was in effect immediately after the sixth day of creation?
First Law of Thermodynamics.The First Law of Thermodynamics (the total quantity of matter and energy is fixed or constant) was in effect immediately after the sixth day of Creation.
What did julius von mayer invent?
German physician and physicists Julius Von Mayer didn't "invent" anything. He actually was the first person to discover and write out the first law of conservation of energy, or first law of thermodynamics.
Why are theories and laws not absolute?
Because they may not apply in all situations.The first law of thermodynamics is true everywhere.The second law of thermodynamics isn't true inside the event horizon of a black holeThe third law of thermodynamics isn't a law but merely a point of reference to make measurements from.Newtonian laws of motion are not absolutely true but are only approximately true but valid for things that travel at less than 1/2 the speed of light.
What are other examples of Third LAw of Motion?
Newton's Third Law of Motion states that bodies simultaneously exert force on each other. Some examples of this law are standing, a bird flying, and a car moving down the road.
Theory of evolution Vs Law of Thermo Dynamics?
The theory of evolution does not vs the law of thermodynamics. They are quite compatible since the earth is an open system.
What is another name for the first law of Thermodynamics?
The first law of thermodynamics is also known as the Law of Energy Conservation.
What law of thermodynamics states that different forms of energy can be converted into one another?
That's related to the First Law of Thermodynamics - the Law of Conservation of Energy.
Which law of Thermodynamics states that energy cannot be created or destroyed?
That law is known as the Law of Conservation of Energy. It is also known as the First Law of Thermodynamics.
When the law of conversation of energy is applied to heat it is known as the law of thermodynamics?
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").
What law of thermodynamics states that energy is neither created or destroyed?
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.
Of thermodynamics is a restatement of the law of conservation?
The 1st Law of thermodynamics is a restatement of the law of conservation of energy.
What is another name for the first law?
Another name for the first law of thermodynamics is the law of energy conservation.
What is universal law of energy?
There is no commonly accepted law by that name, as far as I know. Two important laws about energy are the First Law of Thermodynamics and the Second Law of Thermodynamics.
The first law of thermodynamics is related to the conservation of which quantity?
Yes. There are no known exceptions - otherwise it would not be considered a law
Can energy be produced?
You can't create energy out of nothing (First Law of Thermodynamics); this is an experimentally established fact (i.e., no exceptions are known). Nowadays, the law of conservation of energy (or First Law of Thermodynamics) is often derived from Noether's Theorem, but that is some advanced math.You can convert one type of energy to another, but see also the Second Law of Thermodynamics.You can't create energy out of nothing (First Law of Thermodynamics); this is an experimentally established fact (i.e., no exceptions are known).

What is the relationship between the first law of thermodynamics and the law of conservation of energy?
The first law of thermodynamics states that energy cannot be created or destroyed, only transferred or converted. This is directly related to the law of conservation of energy, which states that the total energy in a closed system remains constant. In essence, the first law of thermodynamics is a specific application of the broader principle of conservation of energy.
How does energy efficiency relate to the first and second law of thermodynamics?
By the first law of thermodynamics, energy is conserved - i.e. the sum of the useful work and the energy lost to heat will equal the energy you started with. The second law states that you will never get 100% energy efficiency.
