Heat Capacity of Silver Iodide. II. Theory

Influence of Sodium and Iodide Ions on the Transformation of Metaphasic Silver Iodide into the Crystalline Silver Iodide

The influence of constitutive (Agl, lions) and nonconstitutive (Na+ ions) components of silver iodide hydrosols on the transformation rate of metaphasic silver iodide into crystalline silver iodide is studied. The simultaneous change of Agl, l ions, and Na+ ions concentrations causes a complex change of the value of the constant k, (which is proportional to the aggregation rate constant k 2). W...

The Heat Capacity of Solid Aliphatic Crystals: II.

In the preceding issue of these PROCZEDINGS, the fact of characteristic frequencies for non-polar bonds was introduced into the Born-Karman heat capacity equations, which were then, with certain approximations, brought into a general simplified form for non-polar compounds.' With the aid of these simplified equations, the heat capacities of some organic solids will now be. calculated and compar...

Negative heat capacity and non-extensive kinetic theory

The negative nature of the heat capacity CV of thermodynamically isolated self-gravitating systems is rediscussed in the framework of a non-extensive kinetic theory. It is found that the dependence of CV on the non-extensive parameter q gives rise to a negative branch with the critical value corresponding to q = 5/3 (CV → −∞).

The reaction of yeast alcohol dehydrogenase with iodoacetamide as determined with a silver-silver iodide electrode.

Heat capacity in proteins.

Heat capacity (Cp) is one of several major thermodynamic quantities commonly measured in proteins. With more than half a dozen definitions, it is the hardest of these quantities to understand in physical terms, but the richest in insight. There are many ramifications of observed Cp changes: The sign distinguishes apolar from polar solvation. It imparts a temperature (T) dependence to entropy an...
