# How to use *Conductivities* in a sentence

Other physical properties of these solutions, such as density, colour, optical rotatory power, &c., like the

**conductivities**, are additive, i.e.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.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**.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.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.AdvertisementThey are white, insulating solids with negligible small electronic

**conductivities**and the bonding is mainly ionic.Conductivity.-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).
