Pertinent statistical mechanical theory is combined with the available measurements of the dielectric constant of water at high temperature and pressure to predict that property at still higher temperature. The dielectric constant is needed in connection with studies of electrolytes such as NaCl/H2O at ...
The dielectric constant of a polarizable water model is estimated for several thermodynamic states at elevated temperatures and reduced densities relative to ambient conditions using molecular dynamics simulations. An extended Lagrangian formulation of induced polarization is used in these simulations in conjun...

The dielectric constant of water was measured for solid samples of sandstone in the frequency range from 5 Hz to 13 MHz with different water contents at room temperature. The two electrode technique was employed. The measurements were made on three samples with different cementation: loamy, loamy...
The value of the static dielectric constant of any material is always greater than one, its value for a vacuum. The value of the dielectric constant at room temperature (25 °C, or 77 °F) is 1.00059 forair, 2.25 forparaffin, 78.2 forwater, and about 2,000 forbarium titanate(BaTiO3)...

inSections 4.1 and 4.2. The values of the dielectric constant for several common solvents at 25oC are given inTable 7.2.1. The dielectric constant also depends on temperature. As an example, the variation of the dielectric constant of water as a function of temperature is shown inFigure 7.2...
of time and then released. The device, which came to be known as theLeyden jar, consisted of a stoppered glass vial or jar filled with water, with a nail piercing the stopper and dipping into the water. By holding the jar in the hand and touching the nail to the conductor of an ...
Temperature As mentioned earlier, charge separation or polarization affects the electric field in a dielectric material. Temperature changes affect polarization and consequently, the dielectric constant. For instance, when water is heated from 0oC to 100oC, its dielectric constant falls from 80 to 55...
