Which metal has the highest conductivity?
At room temperature, silver has the highest electrical and thermal conductivity of all the (known) metals. Note that diamond, an allotrope of carbon, is a poor electrical conductor but is several times better as a thermal conductor than silver. Carbon is a nonmetal, of course, but it was worth mentioning as both a comparison and a curiousity.
What are at least five examples of materials that are good conductors?
copper wire, metals, water, poles, airplanesSilverCopperGoldIronIonized airleadwater with dissolved mineralsgraphiteBut it also depends on which you wish to conduct.For thermal conductivity, the top group, in order of merit, are graphene, diamond, silver, copper.For acoustic (sound) conductivity, you need a rigid non - lossy material, and Beryllium is probably at the top, but with similar metals such as tungsten and steel not far behind.And Brahms and Bach have their followers in the music field.
What is hydraulic conductivity of soil?
This depends on the soil! Cohesionless coarse grained soils with high gravel contents may have high hydraulic conductivity on the order of 1 to 1x10-1 m/s. Mixed sands and gravels are on the order of 1x10-1 to 1x10-3 m/s. Finer sands approximately 1x10-3 to 1x10-4, and fine grained soils such as silty sands may be in the range of 1x10-5 to 1x10-7 m/s. Very fine grained cohesive clay soils have very low hydraulic conductivity values ranging from 1x10-7 to 1x10-13 m/s.
What is electrical energy per order?
It is a concept used to evaluate and compare the cost of different irradiation based water treatments. It is defined as the electrical energy required to reduce the concentration of the compound of interest in 1 m^3 of water by 1 order of magnitude.
In order to provide the power for a heater and lights which device would be appropriate?
Suitable rated separate circuits with MCBs are advisable.
The electrical conductivity of metals which is expressed in ohm-1 m-1 is of the order of?
In the range of 1 x 10^7 1/ohm-m . That's one times ten to the seventh power.
What is doping process?
It is the addition of impurities to a semi-conductor in order improve their electrical conductivity.

Silver is the best electrical conductor but why do some people say Platinum is?
Because they don't know any better. (Plantinum's conductivity is 9,661,000 /ohm.m , Silver's is 63,010,000 /ohm.m ) This would actually be expressed in Siemens. Ohm is a measure of resistance not conductivity. The numbers may be correct however. I haven't done the math. The most conductive of all metals are silver, copper and gold in that order. Silver is also the most thermally conductive element, and the most light reflecting element. Silver also has the unusual property that the tarnish that forms on silver is still highly electrically conductive. Platinum has a much higher melting point than silver and gold ...etc so in some applications, while it is not as good of a conductor, it is the only one that can be used.
What is the old name for Siemens the unit for electrical conductivity?
Old units for electrical conductivity (EC)SI units of electric resistance and electric conductance are ohm (Ω) and siemens (Si). The unit mho ("ohm" in reverse order) for conductance should no longer be used (1 mho = 1 Si). abohm and abmho are older units from the centimetre-gram-second electromagnetic system. statohm and statmho are from the centimetre-gram-second electrostatic system.see also this forum http://landviser.us/phpBB3/viewtopic.php?f=4&t=3&p=19#p19The question is about conductivity, not, as the above answer, conductance. The siemens in the unit of measurement for conductance, whereas the siemens per metre is the unit for conductivity.
What will happen when doped semiconductor is heated will its conductivity increase or decrease?
Doping a semiconductor means to introduce impurities to the semiconductor in order to alter it. For the most part, doping a semiconductor increases its conductivity.
