WebDec 2, 2016 · Thermal conductivity and thermal diffusivity as a function of temperature are estimated from resistivity data using the Wiedemann–Franz law. Data for liquid aluminum obtained by pulse-heating are quite rare because of the low melting temperature of aluminum with 933.47 K (660.32 C), as the fast WebThe thermal capacity of 100 g of aluminum (specific heat = 0.2 cal/g ∘ C) is Q. The heat released by a copper ball of mass 1 kg when cooled from 100°C to 90°C is 8.4 kJ.
