- Title
- Origin of the thermodynamic anomalies of supercooled water
- Plain
- As water is cooled below 0 C without freezing, its response functions grow as if heading toward a singularity. Several competing explanations exist and experiments have not yet chosen among them.
- Precise
- Explain the growth of the isothermal compressibility $\kappa_T$, the isobaric heat capacity $C_P$ and the magnitude of the thermal expansion coefficient $\alpha_P$ in supercooled liquid water at ambient pressure down to about 230 K, distinguishing between the liquid-liquid critical point scenario, the singularity-free scenario, the critical-point-free scenario and the stability-limit conjecture. An answer is a thermodynamic model consistent with all measured response functions in the accessible range and with predictions that experiment can test.
