Not sure,
in my 9th standard (level of Indian standard education),we studied about conductors....."when temperature increases conductivity of a conductor is also increases".
but it is not true in all case because of the properties of the conductors.
in some case ...'temperature increase the resistance of a conductor increases so conductivity decreases '.
for example: in olden days electronic equipments is more efficient when the atmospheric temperature increases or presence of heat .
What else can I help you with?
A material showing perfect conductivity and Meissner effect below a critical temperature?
The Meissner effect refers to the expulsion of magnetic flux when a material becomes superconducting in a magnetic field. A material that shows perfect conductivity is called a superconductor.
How does the conductivity change when the temperature of the material is increased?
When the temperature of a material increases, its conductivity typically also increases. This is because higher temperatures cause the atoms in the material to vibrate more vigorously, allowing for easier movement of electrons, which enhances conductivity.
Define thermal conductivity?
Thermal conductivity is a material property that describes the ability of a material to conduct heat. It is defined as the rate at which heat is transferred through a material per unit of thickness, area, and temperature difference. Materials with high thermal conductivity transfer heat more efficiently than materials with low thermal conductivity.
How does the electrical conductivity of a material change with temperature?
The electrical conductivity of a material generally increases with temperature. This is because at higher temperatures, the atoms in the material vibrate more vigorously, allowing more free electrons to move and carry electric current.
How can one determine the thermal conductivity of a material?
The thermal conductivity of a material can be determined by conducting a thermal conductivity test, which involves measuring the rate at which heat flows through the material. This test typically involves applying a heat source to one side of the material and measuring the temperature difference across the material to calculate its thermal conductivity.
A material showing perfect conductivity and Meissner effect below a critical temperature Is this true or false?
Superconductor

If an iron rod is heated to a high temperature how would it effect its conductivity?
Generally speaking conductivity of metals decreases as the temperature increases.

How does the conductivity of a material change with temperature?
The conductivity of a material generally increases with temperature. This is because higher temperatures cause the atoms in the material to vibrate more vigorously, allowing electrons to move more freely and carry electrical charge more effectively.
Why does conductivity decrease with temperature?
Conductivity decreases with temperature because as temperature rises, atoms and molecules vibrate more vigorously, disrupting the flow of electrons and reducing the ability of the material to conduct electricity.
Thermal conductivity in a sentence?
Thermal conductivity is the property of a material to conduct heat and is defined as the rate at which heat passes through a unit area of the material for a given temperature difference.
How do you calculate thermal conductivity in a material?
Thermal conductivity in a material is calculated by measuring the rate of heat transfer through the material and dividing it by the product of the material's thickness and the temperature difference across it. This calculation helps determine how well a material can conduct heat.
Which of these has the greates effect on the electrical conductivity of solutions?
Influence on the electrical conductivity of solutions:- types of substances dissolved- concentration of solutes- temperature
