Water dependence on temperature

The use of accurate isotope ratio measurement is exemplified here by a method used to determine the temperature of the Mediterranean Sea 10,000 years ago. It is known that the relative solubility of the two isotopic forms of carbon dioxide COj) in sea water depends on temperature... 

It is well known that biopolymers adsorbed water during dry storage and its quality depends on water content. For example the length of keratin depends on water content and therefore it is used as a hygrometer. The amount of adsorbed water depends on temperature and pressure of water vapor. 

It is well known that the atomic ratio of Na/K in natural waters depends on temperature (White, 1965, 1968 Ellis, 1969, 1970). This relationship has been also...

The phase behaviour of systems with low molecular alcohols methanol and ethanol as well as of systems with acetone and propionic acid is relatively simple (pattern I). At lower pressures the single three-phase region is bound by a critical line (L3=L2)Vy at higher pressure the three-phase region is limited by either an upper critical line Lj(L2=V) or the binary three-phase line of the system carbon dioxide-water depending on temperature. 

Plants need water depending on temperature, wind, and sun, also when the owners go on holiday.

The oil fix>tn Zybza field contains 3.78% of organic acids and other compounds that can be hydrolized with alkalies. On that basis, it belongs to high octane petroleums. Tests show the following decrease in surface tension of Zybza crude measured at the boundary with formation water, depending on temperature ... 

Monoglycerides are completely soluble in fats and oils and dispersible in water under certain conditions. Distilled monoglycerides form mesomorphic phases in water depending on temperature, concentration, fatty acid chain length and degree of unsaturation. 

The behavior of bound water in mesoporous silicas was studied by NMR spectroscopy (giving temperature dependence of transverse relaxation time and chemical shift of the proton resonance), XRD (freezing/melting behavior and ice crystalline structure), TSDC (relaxation phenomena for bound water depending on temperature and pore structure), FTIR and Raman spectroscopies (characteristics of adsorption sites and water binding), and other methods (see previous chapters and Sklari et al. 2001, Sliwinska-Bartkowiak et al. 2001). 

Due to the vibrations and rotations of polar molecules, the relative dielectric constant, in a static or slowly alternating field is higher than n. In water, depending on temperature, e, is roughly equal to 80, but n is only 2. 

A large number of studies have dealt with the behavior of water below 0°C (e.g., supercooling of water-in-oil emulsions) and determinations of free and bound water, around OX [20-25]. The crystalUzation enthalpy of water depends on temperature (see Ref. 19), which may be important in supercooled emulsions. Moreover, the difference in the specific heats of ice [2.05 J/(g K)] and water [4.18 J/(g K)] may introduce some error.

As just described, 95% of the water absorbed by plants simply passes through the plant and evaporates into the air. Thus, polymer gels, which absorb and desorb water depending on temperature, are proposed to be used to recycle water prior to its evaporation into the air.

Water consists of two hydrogen and one oxygen atom. The oxygen atom could be a lighter or a heavier isotope (see Fig. 1.6). The evaporation of water depends on temperature.
