Permittivity water
WebSep 12, 2024 · Permittivity varies significantly as a function of frequency. The values below are representative of frequencies from a few kHz to about 1 GHz. The values given are also representative of optical frequencies for materials such as silica that are used in optical applications. Permittivity also varies as a function of temperature. WebJun 12, 2024 · Similarly, a polar solvent - one with a high dielectric constant (relative permittivity $\epsilon_r>\approx15$) - will solubilize polar molecules by forming stabilizing interactions with the solute that compete with solute-solute interactions. Water is a good solvent for polar molecules for the above-mentioned reasons.
