WebIn general, metals (like copper, aluminum, gold, and silver) are good heat conductors, whereas materials like wood, plastic, and rubber are poor heat conductors. Figure 11.4 … WebThe heat capacities of niobium hydride, NbH/sub 0.883/, were measured at 21 to 386 deg K. The weight of the sample used was 47.70 g. The heat capacities of the hydride in the lowtemperature range were much smaller than those of the metal. At temperatures above 300 deg K a continuous and rapid increase of the heat capacity was observed. (P.C.H.) french poet victor crosswordWebIf we look at the heat capacity for the same number of atoms – the molar heat capacity (J/ (mol K) then it is roughly constant (the Dulong Petit law): The heavier elements contain fewer atoms to absorb the energy per gram of material and therefore tend to have lower specific heat capacities. fastnet insurance brokers
