Abstract

The isothermal compressibility and the heat capacity are calculated here using the experimental data for the heat expansion of ice I in the pre-melting region. By analysing the data at various pressures, compressibility and the heat capacity are predicted as functions of temperature and pressure near the melting point (p(m) 202.4 MPa, T-m 252.3 K) in ice I. Our predicted compressibility and heat capacity exhibit anomalous behaviour as the heat expansion in the pre-melting region of ice I.
