The long and short of measuring the electrical conductivity of elements involves little more than making a short piece of "wire" out of a given (pure) element and then applying a voltage and measuring the current. Take into account the external resistance, and the length, cross sectional area and temperature of the element and make some calculations. It's a little more involved with liquids, and tougher still with gaseous elements, but a conductor will "conduct" based on its composition, length, cross sectional area and temperature.
Conductivity of a solution is measured by carrying out the conductivity test with the help of a device known as conductivity analyser. To read the details, you can search in Google or contact the vendors who are into conductivity analysers manufacturing.
There is an instrument made specifically for this purpose. It is called, oddly enough, a conductivity meter. They are used mainly in laboratories and also in industrial settings where a cooling tower is used to cool the building. As water evaporates in the tower, it leaves behind more and more of the minerals and sediment in the basin, which increases the conductivity. The operator uses the conductivity meter to determine when water must be drained and replaced with fresh.
Conductivity is a property of a metal that is independent of the length or thickness of the wire used.
The resistance in ohms of a piece of wire is equal to:
R = length / (conductivity x cross-section area)
So if the resistance and the length and diamter of a piece of wire are measured, the conductivity can be found from:
conductivity = length / (resistance x cross-section area)
The cross-section area is pi/4 times the diameter-squared.
Units of metres should be used for the length and diameter, then the conductivity comes out in its metric units which are siemens per metre.
atached a wire to the object. lay the object on a battery and atatch another wire to the battery if the light bulb lights up it is a conductor.. teachers have tools for this
Conductivity is measured using, believe it or not, a conductivity meter. They measure the resistance/conductivity of the solution.
For the measurement you need a conductivity meter.
depends on the liquid .. mercury yes .. distilled water no ..
Not necessarily. While free movement of molecules in a liquid allows for some degree of conductivity, it does not guarantee conductivity. Conduction depends on the presence of charged particles or ions that can carry electric current through the liquid. So, the ability of a liquid to conduct electricity is determined by the presence of dissolved ions or other conductive substances.
Mud is a solid not a liquid if you wanted to know :]
it is mixture
A liquid is a solution if the mixture has two different substances in it. for Example water is not a solution because it is only H2O, but if you mix water with a drink concentrate that is a solution because the mixture consists of two things
an insulator
what measurement of the liquid. There are many things you can measure in a liquid. weight volume temperature color boiling point conductivity voltage breakdown density specific gravity etc depends on what you are measuring in the liquid. There are many parameters of a liquid you could measure: volume temperature density salinity color conductivity etc
A solution is a mixture of a liquid and a liquid, or liquid and dissolved solids.

Salinity increases conductivity. A saline liquid as a high percentage of sodium which is facilitates the transfer of electrons hence increasing on the conductivity.
A decalitre is one-tenth of a litre. Measure out one decalitre of that liquid and add it to the mixture.

The mixture is homogeneous only when these liquids are miscible.

Sometime it is needed to check purity of a liquid, to check metal content of a liquid.
yeah it is a mixture of solid liquid and gas
