WebIn this paper, the results of heat capacity measurements performed on the polycrystalline Tb1-xErxNi2 intermetallic compounds with x = 0.25, 0.5 and 0.75 are presented. The Debye temperatures and lattice contributions as well as the magnetic part of the heat capacity were determined and analyzed. The heat capacity measurements reveal that the … WebOct 6, 2024 · Now, the speed of sound, v s is not correct for copper according to online tables, and it seems to be closer to 4600 ms − 1. However, I also know that the Debye temp for copper is about 343 K. θ D = ( 1.055 × 10 − 34) ( 4600) ( 1.381 × 10 − 23) ⋅ ( 6 π 2 ⋅ 8.44 × 10 27) 1 / 3 = 279 K. Which just isn't right. WebMar 20, 2024 · The temperature variation of the heat capacity of most metallic solids is well described by Equation \ref{3}. Furthermore, plots of Equation \ref{3} as a function of temperature for metals with widely varying vibrational frequencies reveal that the heat capacity always approaches the same asymptotic limit of \(3R\) at high temperatures. … cvc impound hearing
