Kinetic velocity

Electron density, kinetic velocities, and thermodynamic equilibrium all must be part of the understanding of chemical processes. 98 However, the chemical molecule is not merely the summation of physical properties. Rough approximations can be made for a molecule s overall dipole moment, for example, by adding up individual contributions due to atoms and atomic groups. But... 

The collision rate of polymer molecules should be small due to their low kinetic velocity. This should be accentuated by the high viscosity of the liquid medium consisting of polymer molecules. 

Bernoulli equation = a form of the general energy equation = law of conservation of energy, applied to thermal and fluid flow situations. Particularly, illustrating the interconversion of kinetic (velocity) energy and pressure energy. Also see Venturi, betw = between, billet = See bar, billet, bloom. 

Venturi effect = suction created by conversion of pressure energy to kinetic (velocity) energy.

Alcoholic fermentation is an exothermic reaction (generating heat), and its kinetics (velocity of the reaction) depends strongly on temperature. Several factors affect the course of fermentation (e.g., pH, alcohol concentration, high salt concentration), but temperamre has the greatest effect. Several research studies have shown that the optimum temperature for S. cerevisiae in alcoholic fermentation is close to 32 °C (Costa et al. 2009).

Dsually V is lO to lOO times greater than S. Carriers interact with acoustic phonons by means of a deformation potential O, and a particular carrier eiqperiences all values and directions of kinetic velocity. In ID this is both forward and backward velocity along the chain. The drift velocity V is then a small bias on this kinetic motion due to the applied field. 

In ID the lattice deforms around the electron and loced.ises the electron to form a polaron. The ii portant deformation is acoustic, in udiich the density of the lattice changes optic deformations occur also but are not important in the polaron motion. The mathematical description of the polaron is like that of solitary waves. The Solitary wave Acoustic Polaron (SWAP) has a very large effective mass its kinetic velocity is small. Horeover it cannot move at a velocity greater than S as its kinetic velocity approaches S the acoustic deformation increases and the SNAP mass increases. In addition back scattering is very rare. So the SWAP kinetic and drift velocities are equal.
