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 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.
What is conductance measured in?
The SI unit for conductivity is the siemens per metre. Conductivity is the reciprocal of resistivity, whose SI unit is the ohm metre.
Which of the following has the least effect on lake water temperature?
Shade from surrounding trees has the least effect on lake water temperature.
What effect could thick cloud cover have on the temperature of earths surface?
Thick cloud cover can act as a blanket, trapping heat and causing the surface temperature to increase. Conversely, it can also reflect sunlight back into space, leading to a cooling effect on the surface temperature. The net effect depends on factors such as cloud altitude, composition, and thickness.
How many degrees on average does the greenhouse effect keep the temperature on earth?
Green house effect on average keep temperature of 35-40*c in day &20-25*c in night during summer season.
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 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 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.
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),
When temperature increases resistance increases and conduction decreases why is this is so?
Generally when temperature increases, resistance increases and conduction decreases in metals. In semiconductors, this is generally inverted. First, when temperature increases, the molecular activity of the material increases, making the energy (and activity) of the atoms to be higher. This can make it more difficult for the electrons to participate in the cascade effect that we call electric current, hence increased resistance. Second, conductance is defined as the inverse of resistance; if resistance goes up, then conductance goes down, and vice versa.
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.
What effect temperature?
effect of temperature
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 is effect of dilution on conductance?
The conductance of a given conductor, C = La/l ..(i)\ L = l/Ra ..(ii)The resistance is expressed in units of ohm, the conductance has units of ohm-1 or mho.The conductance of solutions is also governed by the same relations. From (i), if l = 1,a = 1, the specific conductance L = C. That is,the specific conductance (L) is the conductance of the solution enclosed between two electrodes of 1 sq. cm area and 1 cm apart. when you dilute the solution the concentration decrease and the specific conductance also decreaseThe conductance of a solution depends upon the number of ions present and hence on the concentration. To compare the conductivity of different solutions, it is necessary to take the concentration of the solutions into consideration. It is done by using equivalentconductance, l.
