THE TEMPERATURE DEPENDENCE OF UNSTEADY HEAT CONDUCTION IN SOLIDS
Российский технологический журнал, 2019 A mathematical model of the process of unsteady thermal conductivity of solids is proposed in the case where the dependence of the thermal characteristics of the medium (heat capacity, density and thermal conductivity coefficient) on temperature cannot ...

Thermal conductivity of solid CF2Cl2 [PDF]
Low Temperature Physics, 2007 The thermal conductivity of solid CF2Cl2 is measured by the linear-flow method in the temperature range 80–115K under saturated vapor pressure. Special attention is given to the explanation of the heat transfer process under constant density. The temperature dependence of the isochoric thermal conductivity is analyzed within a model in which heat is ...

Thermal Conductivity of Solid Hydrogen
Physical Review B, 1970 The thermal conductivity of solid parahydrogen containing 0.2 to 5% orthohydrogen has been measured over the temperature range 1.5-6 \ifmmode^\circ\else\textdegree\fi{}K. On the low-temperature side of the conductivity maximum, the conductivity shows both a ${T}^{3}$ dependence and a strong dependence on orthohydrogen concentration.
