Temperature effects heat capacity change upon

It is most important to know in this connection the compressibility of the substances concerned, at various temperatures, and in both the liquid and the crystalline state, with its dependent constants such as change of. melting-point with pressure, and effect of pressure upon solubility. Other important data are the existence of new pol3miorphic forms of substances the effect of pressure upon rigidity and its related elastic moduli the effect of pressure upon diathermancy, thermal conductivity, specific heat capacity, and magnetic susceptibility and the effect of pressure in modif dng equilibrium in homogeneous as well as heterogeneous systems. 

Effect of Addition of Inert Diluents. The addition of inert gases to an explosive mixture will have two major effects. It will increase the heat capacity of the mixture, and depending upon the nature of the added gas, it will change the mixture thermal conductivity. Equation 26 shows that an increase in the heat capacity of the mixture will tend to increase the induction period. The addition of a high thermal conductivity gas such as helium will increase the limiting pressure. Rearranging Equation 18 shows that for a given vessel diameter, reactant concentration, and furnace temperature, the ratio... 

Ability of water molecules to form various kinds of local order in condensed state causes variety of its crystalline and amorphous phases at low temperatures. The transitions between liquid water phases with different local orders at low temperatures strongly affect the properties of water at ambient conditions. This effect is presumably responsible for various water properties, which makes water different from most other fluids and often called anomalous (liquid density maximum, heat capacity minimum, etc.). Naturally, the bulk polyamorphism appears also in water properties near surfaces. A transition of liquid water to strongly tetrahe-drally ordered water upon cooling is the most important manifestation of this phenomenon as it occurs at ambient pressures. This transition is extremely difficult to detect in bulk water due to unavoidable crystallization. However, it is observed in many systems containing a confined water owing to the drastic change in various properties.
