Thermal Conductivity Definition

Thermal Conductivity Sentence Examples

• The thermal conductivity of the substance is the constant ratio of the rate of transmission to the temperature gradient.

• Moreover, the variation of thermal conductivity with temperature is small and uncertain, whereas the variation of electrical conductivity is large and can be accurately determined, and may therefore be legitimately utilized for eliminating the external heat-loss.

• By similar reasoning the thermal conductivity of a gas should be independent of the density.

• Another discussed conduction in curved sheets; a third the distribution of electricity in two influencing spheres; a fourth the deter mination of the constant on which depends the intensity of induced currents; while others were devoted to Ohm's law, the motion of electricity in submarine cables, induced magnetism, &c. In other papers, again, various miscellaneous topics were treated - the thermal conductivity of iron, crystalline reflection and refraction, certain propositions in the thermodynamics of solution and vaporization, &c. An important part of his work was contained in his Vorlesungen fiber mathematische Physik (1876), in which the principles of dynamics, as well as various special problems, were treated in a somewhat novel and original manner.

• The measurement of thermal diffusivity by laser flash is an alternative way of determining the thermal conductivity of liquid alloys.
