Abstract
The study presents experimental data of the viscosity and specific heat capacity of the near eutectic gallium–indium–tin alloy. Viscosity data cover the temperature range from the alloy’s melting point of 283.85 K (10.70 °C) to about 370.47 K (97.32 °C). Two independent teams using a capillarity viscosimeter and an oscillating cup viscosimeter obtained almost identical values. Below 373 K (100 °C) the data follow the Arrhenius correlation. Specific heat capacity data result from differential scanning calorimetry measurements and reach from 236 K (− 37 °C) to 340 K (67 °C). The Neumann–Kopp rule gives neither the solid nor the liquid state a satisfactory representation of the data. Approximation functions represent these two regions separately in an excellent manner. The study discusses several issues related to the thermophysical properties, namely melting and crystallisation, and a possible liquid-to-liquid crossover.
期刊介绍：
International Journal of Thermophysics serves as an international medium for the publication of papers in thermophysics, assisting both generators and users of thermophysical properties data. This distinguished journal publishes both experimental and theoretical papers on thermophysical properties of matter in the liquid, gaseous, and solid states (including soft matter, biofluids, and nano- and bio-materials), on instrumentation and techniques leading to their measurement, and on computer studies of model and related systems. Studies in all ranges of temperature, pressure, wavelength, and other relevant variables are included.
