	Thermodynamic Properties of Air
		This applet calculates the thermodynamic properties of air given the pressure and entropy, pressure and density, specific energy and density, entropy and enthalpy, or pressure and temperature, in SI units (kg/m^3, J/kg, J/kg/K, m/s, Pa, K) or British Units (lb/ft^3, BTU/lbm, BTU/lbm/R, ft/s, psi, R).
		Note that the applet is designed especially to allow you to cut and paste in lists of point pairs from other applications such as Excel and, indeed, it is a lot easier to do it this way.
		Press the compute button and the full thermodynamic properties corresponding to each pair of properties is tabulated and displayed in the lower window using the units you selected.

	Thermodynamic Properties Of Air Water Mixtures- Issue Apr-Jun 1999
		Formulations are given for the thermodynamic properties of dry and moist air for pressures between 50 to 5000 kPa.
		The thermodynamic properties of moist air at atmospheric pressure in the temperature range of -60°C < t > 90°C is given in the ASHRAE Handbook - 1997 Fundamentals which is based on Hyland and Wexler formulations.
		The properties of moist air at saturation depend on an iterative determination of the enhancement factor 'f' and mole fractions of air and water vapour in the mixture.

		Liquid helium is a rewarding subject for the study of thermodynamic properties, especially because helium II, the lower temperature phase, exhibits the property of superfluidity.
		Furthermore, the thermodynamic properties are deeply related to the hydrodynamic: for example, the Gibbs free energy is related to the square of the relative velocity between the two fluids.
		The purpose of this paper is to give an account of the equilibrium thermodynamic properties of He II and related quantities such as the velocities of first, second, and fourth sounds and properties of the excitations themselves.

	A SUMMARY OF THERMODYNAMIC FUNDAMENTALS (Site not responding. Last check: 2007-10-15)
		Thermodynamics - the science that is concerned with energy, particularly ‘energy-in-transit’ in the forms of heat and work, and those properties of systems that are related to energy.
		Thermodynamic Properties - any quantity that depends only on the state of a material and is independent of the process by which a material arrives at a given state.
		The thermodynamic variables specified as degrees of freedom are normally temperature, pressure and compositions (mole fractions) of the phases.

	Thermodynamic Equilibrium (Site not responding. Last check: 2007-10-15)
		Thermodynamics is a branch of physics which deals with the energy and work of a system.
		Thermodynamics deals only with the large scale response of a system which we can observe and measure in experiments.
		It is observed that some property of an object, like the pressure in a volume of gas, the length of a metal rod, or the electrical conductivity of a wire, can change when the object is heated or cooled.

	THERMODYNAMIC MODELING
		Thermodynamic equilibrium is some final state of a thermodynamic system insulated from the external medium, i.e., there exists thermal, mechanical and chemical equilibrium in each point of the system and there are no flows.
		In Thermocenter of the Russian Academy of Science during many years is being carried out a theoretical study of thermodynamic properties of individual substances and accumulation of this information in form of the reference book and a database.
		The thermodynamic models necessary to describe the properties of a wide range of phase types are incorporated in the software and database structures.

	Cantera: Species Standard-State Thermodynamic Properties (Site not responding. Last check: 2007-10-15)
		To compute the thermodynamic properties of multicomponent solutions, it is necessary to know something about the thermodynamic properties of the individual species present in the solution.
		For example, the thermodynamic properties of, say, Na+ and Cl- in saltwater are not easily determined from data on the properties of solid NaCl, or solid Na metal, or chlorine gas.
		One common convention for liquid solutions is to use thermodynamic data for the solutes for the limit of infinite dilution in the pure solvent; another convention is to reference all properties to unit molality.

	THERMODYNAMIC MODELING
		Thermodynamic modeling may be treated as a kind of mathematical modeling, and for many years it is used successfully for the investigation of high temperature processes in complex systems.
		We think “thermodynamic computer science” is more appropriate term in this case taking into account that computer is used in thermodynamics not only for calculation purposes but also for gathering, storage, search, treatment, transformation, dissemination and utilization of the data about physico-chemical properties of substances.

	Chemical Science and Technology Laboratory
		Thermophysical properties information (which includes traditional thermodynamic properties) is vital in design, control, optimization, and innovation for products and production processes ranging from chemicals and materials manufacture to energy.
		Also, this experimental competence is vital for validation of the efforts within the Physical and Chemical Properties Division to develop physically based models and simulations to predict properties for systems that currently are not known or for conditions too difficult or expensive to measure.
		NASA representatives cite a study which concluded that property uncertainties account for 70% of the uncertainty in a portion of the propulsion system design, and that the differences in RP-1 properties from different sources can amount to 5% to 60%.

	Thermodynamic Properties
		The exceptions arise because the thermodynamic properties of small clusters are discontinuously dependent on N and because the volume of a cluster is hard to define[
		One feature of the superposition method is that it allows one to restrict the regions of configuration space considered, and hence to look at thermodynamic properties which would be difficult to obtain by other methods.
		For example, we can study the thermodynamic effects of structural relaxation in the absence of a transition to the solid-like state, thus enabling us to study supercooled liquid-like and perhaps even glass-like clusters.

		In thermodynamics, a system is a region of space of which we have some interest.
		Most thermodynamics problems involve finding the heat and work flows that must be supplied to (or removed from) the system to obtain the desired result.
		An understanding of such diagrams is essential to thermodynamics because there will be many occasions in which you will have to refer to a phase diagram (or a tabular representation of one) in order to obtain needed property information.

		Ideal and dilute gas properties, also in SI units calculated from the equations are tabulated at 20 K and at 20 degree Celsius intervals from the melting temperature to 1000 K. In the absence of experimental data, the tabulated data are extrapolated values and these are indicated in the tables.

	heat transfer fundamentals, thermodynamic properties, thermal conductivity, thermal insulators, thermal insulation
		Radiation is the transfer of heat energy by electromagnetic (infrared) waves and is very different from conduction and convection.
		The most important principle in infrared heating is that infrared energy radiates from the source in straight lines and does not become heat energy until absorbed by the work product.
		These constants are used in the evaluation of the materials and in heat energy calculations.
