Volume kinetic

The state (or behaviour) of a system is described by variables or properties which may be classified as (a) extensive properties such as mass, volume, kinetic energy and (b) intensive properties which are independent of system size, e.g., pressure, temperature, concentration. An extensive property can be treated like an intensive property by specifying that it refers to a unit amount of the substance concerned. Thus, mass and volume are extensive properties, but density, which is mass per unit volume, and specific volume, which is volume per unit mass, are intensive properties. In a similar way, specific heat is an intensive property, whereas heat capacity is an extensive property. 

The bubble energy is conveniently expressed as the sum of the pressure-volume work, 6pV, the surface kinetic energy, eSKl the surface potential energy, eSP, and the volume kinetic energy, eVK, arising from the removal of atoms from the cavity boundary to the bulk of the liquid. 

It should be noted that even though concentration terms are expressed based on the total culture volume, kinetic parameters still remain on a biotic phase basis in the formulation.

The reversion of gelatins to collagen has also been discussed with refer ence to cross-links. The denaturation of collagen results in marked changes of viscosity, optical rotation, molecular weight, volume, kinetics of proteolysis, and other properties. Under certain conditions a partial reversal of these changes can be achieved (Flory and Garrett, 1958 von Hippel...

As in previous volumes, kinetic data are reported in the form E or log A or and or units (SI or other) used in the original article, although some conversions have been made both in the text and in the tables where comparisons are required.

It is not possible at this point to make a completely definitive statement about the sintering mechanism or mechanisms in alumina. However, most of the kinetic data seem to indicate grain boundary diffusion kinetics. The most completely characterized powder (sized Alcoa A-14) followed the grain boundary model very closely after a small, temperature-independent length correction and a short volume kinetics portion. Clustered powders either... 

Equations relating x and t have been derived for simple geometrical systems assuming (1) the reaction rate is phase-boundary controlled, (2) the reaction rate is proportional to the surface area of the fraction of unreacted material, and (3) the nucleation step occurs virtually instantaneously so that the surface of each particle is covered with a layer of product. The models developed from the foregoing boundary conditions are termed phase boundary or contracting volume kinetic models. For a sphere reacting from the surface inward ( ) the relationship between x and t is...
