	Third law of thermodynamics - Wikipedia, the free encyclopedia (Site not responding. Last check: 2007-10-21)
		The Third Law states that the entropy of a system at ZAT is a well-defined constant.
		In simple terms, the Third Law states that the entropy of a pure substance at ZAT is zero.
		The Third Law was developed by Walther Nernst, during the years 1906-1912, and is thus sometimes referred to as Nernst's theorem.

		Established in the 19th century, the Kelvin-Planck statement of the second law of thermodynamics says, "It is impossible for any device that operates on a cycle to receive heat from a single reservoir and produce a net amount of work." This was shown to be equivalent to the statement of Clausius.
		The second law of thermodynamics is important to engineers because it provides a way to determine the quality, as well as the amount of degradation of energy during a process.

	Thermodynamics - Wikipedia, the free encyclopedia
		Thermodynamics (from the Greek thermos meaning heat and dynamis meaning power) is a branch of physics that studies the effects of changes in temperature, pressure, and volume on physical systems at the macroscopic scale by analyzing the collective motion of their particles using statistics.
		Classical thermodynamics is the original early 1800s variation of thermodynamics concerned with thermodynamic states, and properties as energy, work, and heat, and with the laws of thermodynamics, all lacking an atomic interpretation.
		Thermodynamic processes which develop so slowly as to allow each intermediate step to be an equilibrium state are said to be reversible processes.

		Authors: Belgiorno, F. Martellini, M. We discuss in the framework of fl hole thermodynamics some aspects relative to the third law in the case of fl holes of the Kerr-Newman family.
		In the light of the standard proof of the equivalence between the unattainability of the zero temperature and the entropic version of the third law it is remarked that the unattainability has a special character in fl hole thermodynamics.
		The third law of fl hole dynamics by W.Israel is then interpreted as a further strong corroboration to the picture of a discontinuity between extremal states and non-extremal ones.

		The ´´zeroth law´´ states that this relation is transitive, which means that whenever system A is in thermal equilibrium with B, and B is in thermal equilibrium with system C, then A and C are also in thermal equilibrium.
		It is often claimed, for instance by Max Planck in his influential textbook on thermodynamics, that this law proves that we can define a temperature function, or more informally, that we can ´construct a thermometer´.
		However, the need to state it explicitly as a law was not perceived until the first third of the 20th century, long after the first three laws were already widely in use and named as such, hence the zero numbering.

		The Second Law of Thermodynamics states that "in all energy exchanges, if no energy enters or leaves the system, the potential energy of the state will always be less than that of the initial state." This is also commonly referred to as entropy.

	What is a simple defintion of the laws of thermodynamics?
		Thermodynamics is the study of the inter-relation between heat, work and internal energy of a system.
		However, since their conception, these laws have become some of the most important laws of all science - and are often associated with concepts far beyond what is directly stated in the wording.
		To give you a better understanding on how these laws came about and their modern scope of coverage, you have to understand when and why these laws were generated.
