yes temperature affects the conductivity of conductor and semi conductors but in case of insulators temp. has no effect. While we talk about conductors as temp. increases conductivity decreases ,the question is why, look if we take an example of copper the conductivity is so high at normal temperature because the molecules in the copper are so close but when we increase temperature the inter molecule distance increases and result is increasing resistance of the copper, and as we know that resistance is inversely proportional to the conductivity. So in the case of conductor, temperature affects the conductivity.
Hey may be you are familiarize with the new aspect called superconductivity, the same effect is here while the temperature of a conductor is so low approximately -273degree the conductor becomes superconductor because Resistance become so low (can say approx. 0 but not exact 0).
You should know that most metals increase their electrical resistivity by about 0.005 per degree.
Good luck

What else can I help you with?
Why you caluculate the corrected conductance?
Corrected conductance is calculated to account for the impact of temperature on the conductance of a substance. Conductance is temperature-dependent, so correcting for this allows for a more accurate comparison of values across different temperatures. It helps to standardize conductance measurements and make them more reliable for analysis.
What is the effect of temperature on conductance?
If you're talking about electrical conductance of a wire, I think increased temp means decreased conductance. Because the metal atoms vibrate faster with increased temp, so the electrons collide with the atoms more frequently, therefore find it more difficult to get through the wire
What is the difference between specific conductance and conductivity?
me too searching!!
What is mean by corrected conductance?
Corrected conductance refers to the process of adjusting measured conductance values to account for factors like temperature, electrode distance, or sample concentration. By correcting for these variables, researchers can ensure that conductance measurements are more accurate and comparable across different conditions or samples.
How will molar conductivity vary with concentration or temperature?
Molar conductivity typically decreases with increasing concentration due to increased ion-ion interactions at higher concentrations. Additionally, molar conductivity generally increases with temperature due to enhanced ion mobility and decreased viscosity of the electrolyte solution.
Is the change in resistance and conductance inversely linear?
Yes, the change in resistance and conductance is inversely linear. Resistance (R) and conductance (G) are related by the equation ( G = \frac{1}{R} ). As resistance increases, conductance decreases proportionally, and vice versa, demonstrating their inverse relationship. This relationship holds true as long as the material and temperature remain constant.
What is the difference between specific conductance and equivalence conductance?
Specific conductance is the conductance of a specified length of a substance, typically 1 cm, while equivalence conductance is the conductance of all ions produced by one mole of an electrolyte in solution. Specific conductance is a property of the substance itself, whereas equivalence conductance is a property of the electrolyte in solution.
What is conductance titration?
Conductance titration works on the principle of ohm's law. If we are to find the strength of a acid then we take that acid into a beaker and dip the electrode of conductometer into the acid solution. This measures the conductance of acid. Now, we titrate this acid solution against the base of known molarity, the conductance starts decreasing. This is due to the binding of H+ ions of acid with the OH- of Base until a point is reached where conductance is minimum. When we move forward the conductance starts increasing again. This is now due to the free ions of Base present in solution. The conductance produced by an ion is proportional to its concentration (at constant temperature),
What is a coulomb blockade thermometer?
A Coulomb blockade thermometer is a sensitive device used to measure temperature by detecting changes in electrical conductance at low temperatures. It operates based on the Coulomb blockade effect, where the transport of electrons is blocked due to the device's small size and low temperature conditions. By monitoring the device's conductance, precise temperature measurements can be obtained.
What is specific conductance of 0.02 molar KCl solution?
The specific conductance of a 0.02 M KCl solution would depend on the concentration of KCl and the temperature. Specific conductance is measured in Siemens per meter (S/m) and is directly proportional to the concentration of the electrolyte solution.
How are specific conductance and equivalent conductance related to concentration of electrolyte?
Specific conductance is directly proportional to the concentration of electrolyte, while equivalent conductance is inversely proportional to the concentration of electrolyte. This is because specific conductance is the conductivity of a solution normalized to a unit concentration, while equivalent conductance is the conductivity of a solution containing one equivalent of the electrolyte.
What happens to the current if the conductance decreases?
If conductance decreases, the current flowing through the circuit will also decrease. Conductance is the inverse of resistance, so decreasing conductance means increasing resistance, which impedes the flow of current.
