The highconductivity of the metal necessitates this, as any supply of molten welding rod before the edges are in a molten state inevitably produces adhesion.
Owing to the high conductivity of copper, a relatively larger blowpipe tip must be used than when welding either iron or mild steel of the same thickness.
He enhanced the value of his device by the vital discovery that the conductivity bestowed upon filings by electric discharges could be destroyed by simply shaking or tapping them apart.
He then communicated a paper 'On the Selective Conductivity exhibited by Polarising Substances,' which was published by the Royal Society, in January 1897.
He next read, at the Glasgow meeting of the British Association, in 1901, a paper 'On the Conductivity of Metallic particles under Cyclic Electro-magnetic Variation.
The transference of heat is also proportional to the conductivity of the metal forming the heating surface.
The electrical conductivity of crystals also varies with the direction, and bears the same relation to the symmetry as the thermal conductivity.
In conductivity this metal is only exceeded by copper, having many times that of iron.
When applied to the generation of steam, this material will enable us to carry higher pressure at a reduced cost and increased safety, as this will be accomplished by the thinner plate, the greaterconductivity of heat, and the better fiber.
Bill, doesn't that gravitor's field work by conductivity of some sort through the surrounding material?
Its electronic conductivity is more efficient, so we're getting far more power from those flashlight batteries.
The maximum conductivity of flow of heat for any given material is secured by so designing the boiler as to secure rapid, steady, and complete circulation of the water within it.
Iron is largely used as an electrical conductor, so that it is well to know how its conductivity is affected by ordinary admixtures.
Of course, engineers and mechanics were much interested in a metal only about one-third as heavy as brass or copper, of white lustre, and with as much as five-eighths the electrical conductivity of copper.
Tenacity and conductivity for heat, as an example, go together; all the tenacious metals as a group are conducting as well.
At first steel was valued for its strength and elasticity; to-day we also inquire as to its conductivity for heat or electricity, its behavior in powerful magnetic fields, its capacity to absorb or reflect rays luminous or other.
Observations concerning the effect of light upon the conductivity of selenium had employed the galvanometer solely; it occurred to me that the telephone, from its extreme sensitiveness, might be substituted with advantage.
Every portion of the conductor was submitted to a searching test, and all copper of a lower conductivity than 85 per cent.
It would appear, however, that liquids, such as water and glycerin, differ remarkably little in conductivity in spite of enormous differences of viscosity.
The wax was observed to melt first on the bismuth, although its conductivity is less than that of iron.
According to the kinetic theory of gases, the conductivity of a gas depends on molecular diffusion.
This is quite incorrect, because the conductivity of iron is about six times that of bismuth, and the rate of propagation of a temperature wave is therefore twice as great in iron as in bismuth.
It was for some time doubted whether a gas possessed any true conductivity for heat.
It is often stated on the strength of this experiment that the rate of propagation of a temperature wave, which depends on the ratio of the conductivity to the specific heat per unit volume, is greater in bismuth than in iron (e.
But this is of less account, because the conductivity of water is much greater than that of air, and because the film is continually broken up by the formation of steam, which abstracts heat very rapidly.
A bar of lead similarly treated will show a faster rate of propagation than iron, because, although its conductivityis only half that of iron, its specific heat per unit volume is 2.
In fact, the jointconductivity will be the sum of the two separate conductivities.
Silver is taken as the standard, with the percentage of 100, and the conductivity of all other metals is expressed in hundredths of the conductivity of silver.
Conductivity is, as shown before, the reciprocal of resistance.
I should have inserted it under the heading of remedies that interrupt the conductivity of nerves, and thus give the centres temporary rest.
Similar considerations ought to be kept in view when determining the energy of acids by means of the electrical conductivity of their weak solutions.
Elements alone, although not all of them, have the peculiar lustre, opacity, malleability, and the great heat and electrical conductivity which are proper to metals and their mutual combinations.
When carbon brushes are used, it is desirable that the current be small, because, on account of the low conductivity of the carbon, more contact area is necessary than with copper for equal current transmission.
Carbon brushes would not be suitable for this class of machine because even with copper brushes, whose conductivity is much higher than carbon, the commutator must be of considerable size to give the required brush contact area.
Professor Trowbridge have proved beyond a doubt that, by means of such delicate apparatus as the telephone and microphone, it is possible for the observer to state in which direction, from a given point, the best line of conductivity runs.
Deflections of the compass, due to the passing of earth-currents along the natural lines of conductivity in the soil or the rocks, are so frequently noticed as to be a source of calculation to the scientific surveyor and astronomer.
Gray[111] has found that this increase in conductivity is only transitory and disappears in fifteen minutes.
McClendon[110] has shown that the electrical conductivity of the egg is increased after fertilization, and J.
The peroxide of manganese, which forms the base of an excellent battery for giving a small rendering, possesses at first better conductivity than oxide of copper, but this property is lost by reduction and transformation into lower oxides.
This great constancy is chiefly due to the progressive reduction of the depolarizing electrode to the state of very conductive metal, which augments its conductivity and its depolarizing power.
Whether gases possess conductivityis open to discussion, but this is certain, that such power is very small.
In the last few years it has been discovered that the auriculoventricular handle, or "bundle of His," has a necessary function of conductivity of auricular impulse to ventricular contraction.
The above list will hopefully give you a few useful examples demonstrating the appropriate usage of "conductivity" in a variety of sentences. We hope that you will now be able to make sentences using this word. Other words: conductance; conduction; conductor; dielectric
