conductivities's Usage Examples:

0562; its thermal and electrical conductivities are 145 to 152 and '14.

The following table gives the electric conductivities of a number of metals as determined by Matthiesen, and the relative internal thermal conductivities of (nominally) the same metals as determined by Wiedemann and Franz, with rods about 5 mm.

"Neglecting the external heat-loss, and the variation of the thermal and electric conductivities k and k', we obtain, as before, for the difference of temperature between the centre and ends, the equation O, Tho z Go C 2 R1/8qk ECl/8qk E 2 k'/8k, (11) where E is the difference of electric potential between the ends.

- Observation of the steady distribution of temperature along a bar heated at one end was very early employed by Fourier, Despretz and others for the comparison of conductivities.

Neglecting the external heat-loss, and the variation of the thermal and electric conductivities k and k', we obtain, as before, for the difference of temperature between the centre and ends, the equation O, Tho z Go C 2 R1/8qk ECl/8qk E 2 k'/8k, (11) where E is the difference of electric potential between the ends.

, 1867-68), Tait was led to the conclusion that " the thermal and electric conductivities of metals varied inversely as the absolute temperature, and that the specific heat of electricity was directly proportional to the same.

On mixing dilute solutions of the diazonium hydroxide and the alkali together, it is found that the molecular conductivity of the mixture is much less than the sum of the two electrical conductivities of the solutions separately, from which it follows that a portion of the ions present have changed to the non-ionized condition.

The conductivities of thin slices of crystals have been measured by C.

the electrical conductivities of normal solutions of the acids have been tabulated.

, like the conductivities, are additive, i.

-Conductivity, whether thermic or electric, is very differently developed in different metals; and, as an exact knowledge of these conductivities is of great importance, much attention has been given to their numerical determination (see Electric conduction; and Conduction Of Heat).

They found that the absorbing powers of the metals, and therefore, by the principle of exchanges, their radiating powers also, are proportional to the square roots of their electric conductivities.
