Dielectric Constant of Undercooled Water.

Abstract

Recent work has shown that liquid water has anomalous thermodynamic properties in its metastable undercooled state, below 0 C. We have investigated the static dielectric constant and conductivity of undercooled water by mesuring the capacitance (within 0.05%) and conductance (within 0.2%) of water-filled glass capillary capacitance cells between +20 C and -17 C. We find that the capacitance and conductance data over the entire temperature range can be represented by analytic functions. Our measurements show no evidence of anomalous behavior in the dielectric constant or conductivity of undercooled water. (Author)
