  Thermodynamics
Thermodynamics is the study of energy, its conversions between various forms such as heat, and the ability of energy to do work.
It can be argued that thermodynamics was misnamed as it does not actually relate to rates of change as such and therefore would probably have been better called thermostatics as a field.
Zeroth law: A fundamental concept within thermodynamics, however, it was not termed a law until after the first three laws were already widely in use, hence the zero numbering.

 Chemical thermodynamics - Wikipedia, the free encyclopedia
In thermodynamics, chemical thermodynamics is the mathematical study of the interrelation of heat and work with chemical reactions or with a physical change of state within the confines of the laws of thermodynamics.
Chemical thermodynamics can be generally thought of as the application of mathematical methods to the study of chemical questions.
The primary objective of chemical thermodynamics is the establishment of a criterion for the determination of the feasibility or spontaneity of a given transformation.

 Gibbs & Chemical Thermodynamics   (Site not responding. Last check: 2007-11-04)
The case of chemical thermodynamics is the most expressive, however: it was due to appearance of highly perfect and completed system created by Glbbs, that chemical thermodynamics had been really divided into two different branches which were conventionally designated as 'pre-glbbsian' and 'gibbsian' chemical thermodynamics [5].
It is the result of absorption the Gibbs' legacy, that the necessity of obtaining the explicit analytic expressions for the chemical potentials of components, or for the free energy of a system as a whole, had been clearly understood in chemical thermodynamics.
The only elucidation here is that the intrusion of statistical mechanics ideas upon chemical thermodynamics had the general cause in its continuous broadening: the more became the variety of objects studied by chemical thermodynamics, the more became the variety of structures to be included into consideration.

 Chemical thermodynamics
Thermodynamics is a classic scientific discipline of singular logic and rigor, the results of which are of great general applicability.
A chemical reaction taking place in a solution contained in a beaker on a laboratory bench can also be treated as a closed system, at least if no gases are produced or consumed in the reaction, and if our critical observations are made on a time scale over which evaporation of solvent is insignificant.
Perhaps our single most important goal in studying such systems of chemical reactions is to understand that the process by which they spontaneously approach the state of equilibrium is determined by progress toward a minimum of a thermodynamically defined function of the state of the system called the free energy.

 Chemical Thermodynamics
Thermodynamics is the study of energy changes accompanying physcial and chemical changes.
Heat of fusion is the heat required to melt a substance at is normal melting temperature, while the heat of vaporization is the heat required to evaporate the substance at its normal boiling point.
Chemically, that usually means energy is converted to work, energy in the form of heat moves from one place to another, or energy is stored up in the constituent chemicals.

 Thermodynamics - Wikipedia, the free encyclopedia (via CobWeb/3.1 planet03.csc.ncsu.edu)   (Site not responding. Last check: 2007-11-04)
Thermodynamics (from the Greek thermos meaning heat and dynamics 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.
Chemical thermodynamics is the study of the interrelation of heat with chemical reactions or with a physical change of state within the confines of the laws of thermodynamics.
Thermodynamic processes which develop so slowly as to allow each intermediate step to be an equilibrium state are said to be reversible processes.

 Thermochemistry - Wikipedia, the free encyclopedia
In thermodynamics and physical chemistry, thermochemistry is the study of the heat evolved or absorbed in chemical reactions.
In 1780 Antoine Lavoisier and Pierre-Simon Laplace laid the foundations of “thermochemistry” by showing that the heat evolved in a reaction is equal to the heat absorbed in the reverse reaction.
With the advent of the mechanical theory of heat in the early 19th century, Hess’s law came to be viewed as a consequence of the law of conservation of energy.
