Conductivity Of Metals Sorted By Resistivity. The heat out-flow was derived both from the gradient in another Armco iron rod attached to the lower end of the specimen and by the water-flow calorimeter at the base of this iron rod. Atomic Mass Number – Does it conserve in a nuclear reaction? Latent Heat of Fusion of Iridium is 26.1 kJ/mol. The enthalpy of vaporization is a function of the pressure at which that transformation takes place. This is due to use of a revised calibration for the nickel-chromium and Constantan thermocouples used. At temperatures exceeding θ, where the theoretical value of the Lorenz number should hold, any excess above the theoretical value can be attributed to augmentation of the thermal conductivity by phonon or lattice conduction.

The atoms of metal elements are characterized by the presence of … Electrical conductivity and its converse, electrical resistivity, is a fundamental property of a material that quantifies how Iridium conducts the flow of electric current. For resistivity measurements at liquid helium temperatures a comparison method was used in which the potential drops operated in opposition through a galvanometer, and the currents in the standard resistance and the specimen circuits were adjusted to give no deflection. The macroscopic magnetic properties of a material are a consequence of interactions between an external magnetic field and the magnetic dipole moments of the constituent atoms. As the temperature is reduced towards and below the characteristic temperature, 8, the relaxation times associated with electric and thermal electronic transport are no longer comparable, hence the observed decrease towards lower values for the Lorenz number that commences in the range 300° to 400°K.
