It was originally based on observation. Nowadays it is derived from Noether's Theorem. In summary, it is related to the fact that the laws of physics don't change over time. Noether's Theorem uses some fairly advanced math; but if you want to investigate, you can get some initial information here: http://en.wikipedia.org/wiki/Noether's_Theorem

"Unavailable for doing work" is related to the Second Law of Thermodynamics.
Second Law of Thermodynamics
The Second Law of Thermodynamics.
Thermodynamics is both a law and a theory. It has a set of well-established laws, such as the first and second laws of thermodynamics, which describe the behavior of energy in systems. Additionally, the principles and concepts underlying thermodynamics are formulated into a theory to explain and predict the behavior of physical systems.
the internal energy (thermal energy)

Entropy is closely related to the 2nd law of thermodynamics, not the 1st law. The 1st law of thermodynamics states that energy cannot be created or destroyed, only transferred or converted. Entropy, on the other hand, is a measure of the disorder or randomness of a system, which increases over time according to the 2nd law of thermodynamics.
The 1st Law of thermodynamics is a restatement of the law of conservation of energy.
conservation of energy law .
The first law of thermodynamics states that the energy of an isolated system is constant.
The first law of thermodynamics is the conservation of energy applied to thermal systems, stating that energy cannot be created or destroyed, only transferred or transformed in a system.
The second law of thermodynamics dictates that heat energy will naturally flow from a hotter object to a cooler object when they come into contact. This law describes the direction of heat transfer between objects and the associated increase in entropy in the system.
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").
Thermodynamic cycle is based on 2nd law of thermodynamics.
The first law of thermodynamics is also known as the Law of Energy Conservation.
"Unavailable for doing work" is related to the Second Law of Thermodynamics.
That law is known as the Law of Conservation of Energy. It is also known as the First Law of Thermodynamics.
