in the dielectric constant of moist clay with water content, it was assumedthat the dielectric constant of the water increased exponentially from 3 (the high-frequency value for ice) at the water – clay boundary to 80 (the normal value for water) at an infinite distance from the boundary....
The experimental static dielectric constants ([epsilon]) of water formulated by Fernández, et al., (1997-International Association for the Properties of Water and Steam, IAPWS), –35 to 600^o^C; 0.1 to 1200 MPa, are discovered to be closely described throughout by a simple equation of den...

1. Understand the Relationship: The permittivity of a medium (ϵ) is related to the permittivity of free space (ϵ0) and the dielectric constant (ϵr) of the medium by the formula: ϵ=ϵr⋅ϵ0 2. Identify Given Values: - Dielectric constant of pure water (ϵr) = 81 -...
- The dielectric constant K of pure water is 81. - The permittivity of free space ε0 is approximately 8.85×10−12C2/N m2. 4. Substitute the Values: Now, substitute the known values into the equation: ε=81⋅(8.85×10−12) 5. Perform the Calculation: ε=81⋅8.85×10−12=...
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. Thus, th...
The Onsager and Kirkwood theories of polar dielectrics are extended to give expressions for the dielectric constant at high field strengths. The theory is applied in detail to water and simple formulas for the dielectric constant in terms of well‐known quantities are obtained. The results of the...
