It is related to the 2nd law of thermodynamics

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

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

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

They have the same genus - "URSUS". *1st part of scientific name is the genus, 2nd is the species

Energy flows from one type toanother following the laws of thermodynamics. The 1st law states that no energy is created or destroyed, and the 2nd law states that energy will move from an area of high concentration to an area of low concentration or that the entropy of a closed system will remain constant or diminish.

You can't get ahead (1st law - conservation of energy - you can't get more energy out than you put in) You can't even break even (2nd law - 100% efficiency is not possible - some energy will always be lost as heat to the surroundings, thus increasing the overall entropy of the universe) You can't get out of the game (no real process is reversible)

The first law of thermodynamics states that you can't create or destroy energy. The second law of thermodynamics has been formulated in several ways; one of them is that useful energy is constantly being converted to useless energy - in other words, with respect to energy, there are irreversible processes in nature.

The first law of thermodynamics is also called the law of conservation of may be stated as: 1st Statement: in this universe energy can neither be created nor destroyed though it may change from one form to another.

1st law: Enery can neither be created nor destroyed,but it can be transformed from one place to other. 2nd law: (i) No heat engine is more efficient than tha theoretical carnot engine. (ii) In a closed system entropy can never decrease. (iii)There are irreversible processes. 3rd law: If the kinetic energy of all the molecules is removed then a state called absolute zero will occur.

Transfer of energy is explained by 1st law of thermodynamics. According to first law of thermodynamics , energy can be transferred or transformed form one form or the other but the total quanta of energy remains constant. The total energy in the universe is constant.

Nothing. 1st Law of Thermodynamics: energy cannot be created or destroyed, it can only change form.

I like the quote from Charles Percy Snow, Baron Snow, CBE (or possibly Allen Ginsberg - depending on who you ask) which applies equally well to thermodynamics and ultimately gambling. 1st Law: You'll never get ahead of the house - or - you can't win 2nd Law: not only that - you'll never break even.(the house always takes its percentage) In more scientific terms: 1st Law - the energy of the universe is conserved in any process - or - you can neither create no destroy energy. With the famous equation E=mc², we have to modify that to say that the matter and energy of the universe is constant - or - you can't create or destroy matter/energy - just change its form. 2nd Law - you cannot covert all energy in the form of heat to an equivalent amount of work - some will be lost as heat to the environment - or - You cannot create a heat engine which extracts heat and converts it ALL to useful work - or - whenever any source of energy is used to do work, there will always be an increase in the entropy of the universe from the heat lost from the process (in this case we might think of entropy as the "house" in gambling).

1st. Principle-- If two bodies are in thermal equilibrium with a third body, they are also in thermal equilibrium with each other. 2nd. Principle-- Heat energy and mechanical work are mutually convertible. 3rd.-- It is impossible to construct a mechanical device ( engine) whose sole purpose is to convert all of the heat energy supply to it into equal amount of work. 4th.-- The entropy of a pure crystalline substance at absolute zero temperature is zero

Anywhere from 0% to 99%+. Below 0% is impossible; there is no such thing as negative work. 100% and above is impossible by the 1st and 2nd laws of thermodynamics.
