The sound velocity in metastable liquid water under atmospheric pressure

Abstract

Ultrasonic sound velocity data in supercooled water are analyzed in the light of present theories. Preliminary evidence for a minimum in the sound speed versus temperature curve is shown to be consistent with available data for other thermodynamic properties. A simple two‐state mixture model combined with experimental data may be used to yield similar evidence. Sound speed data in superheated water are used to determine other thermodynamic parameters in the 100 to 170 °C temperature range under atmospheric pressure.
