Thermodynamic components of freezing stress

Journal of Theoretical Biology, 1973
Abstract A biophysical basis is provided for finding functional components of freezing stresses in plant genotypes. Potential energies of water associations with plant substances, activation energies of transitions of water distributions, and inhibition of freezing kinetics are major plant characteristics which interact with environmental variables ...

Components in Chemical Thermodynamics

Journal of Chemical Education, 1995
Chemical equations are actually matrix equations, and this has important implications for their thermodynamic treatment. The fundamental equation for chemical thermodynamics for a chemical reaction system can be written in terms of species, but at chemical equilibrium, it has to be written in terms of components.

THERMODYNAMIC CALCULATION OF n-COMPONENT EUTECTIC MIXTURES

International Journal of Modern Physics C, 2004
This paper presents a simple numerical method to calculate the eutectic mixture composition and melting temperature. Using a Newton–Raphson method to solve the nonlinear problem, the calculation is possible for n-component eutectic. We tested this algorithm on inorganic and organic mixtures.

High-Temperature Thermodynamic Properties of Mars-Atmosphere Components

Journal of Spacecraft and Rockets, 2004
Methods of calculation of high-temperature thermodynamic properties for some selected Mars-atmosphere components in the temperature range from 200 to 50.000 K and results are discussed and compared with previous works. Aspects such as quasi-bound rotational states, cutoff criteria, and autoionizing states are considered.

Thermodynamic Properties of High-Temperature Air Components

1996
The paper gives a synthetic description of the basic methods to calculate the high-temperature thermodynamic properties of air species. Emphasis is given to the strong dependence of the electronic partition function and the thermodynamic properties of atomic species on the number of electronic levels taken into account.

Thermodynamics of Three-Component Systems

Nature, 1952
ALTHOUGH relations of the type where a is activity, n is number of moles, and the suffixes denote the components, are by no means new1, they have been little exploited. Further types such as and

Components and Thermodynamic Cycles

2019
Although many technical components, that are required to run energy conversion processes, have already been discussed previously, the focus in this chapter is on thermal turbo-machines as well as on heat exchangers. However, in this chapter the technical components are treated in steady state operation.

Thermodynamics of Segregation in Multi-Component Alloys

MRS Proceedings, 1988
Thermodynamic equations are developed to express segregation in multicomponent alloys. These equations use concepts of excess partial free energies and activity coefficients and can be used in a wide variety of situations, including those where the segregating elements, such as sulfur, form strong chemical compounds in the bulk. A lower surface tension

Components of the Thermodynamic Functions of Iron

Physical Review, 1956
The thermodynamic functions enthalpy, entropy, and free energy of alpha and gamma iron are determined from existing data. These functions are resolved into their magnetic, lattice, and electronic components on the basis of additivity of the respective specific heat components.
