Calorimetric study of Wood alloy①
(Dalian Institute of Chemical Physics, Chinese Academy of Sciences, Dalian 116023, P.R.China)
Abstract: The heat capacities of Wood alloy have been measured with an automatic adiabatic calorimeter over the temperature range of 80~360K. The thermodynamic data of solid-liquid phase transition have been obtained from the heat capacity measurements. The melting temperature, enthalpy and entropy of fusion of the substance are 345.662 K, 18.47 J·g-1and 0.053 43 J·g-1·K-1, respectively. The necessary thermal data are provided for the low temperature thermodynamic study of the alloy.
Key words: Wood alloys; calorimetry; heat capacity; melting points; fusion enthalpy
