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.
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.
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.
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.
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.
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.
Superconductor
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.
b'coz super conductivity is achieved only when the material is cooled below a critical temperature. if it cooled above the critical temp. than the material ceases to be a super conductor. to maintain it conductivity helium and liquid nitrogen which is not easy 2 be used that is why super conductor can't be used for commercial purposes in our day to day life

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.
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 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.
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.
Temperature affects conductivity by influencing the movement of charged particles within a material. Generally, as temperature increases, the conductivity of a material also increases because higher temperatures provide more energy for charged particles to move freely, carrying electrical current more effectively. Conversely, lower temperatures restrict the movement of charged particles, leading to lower conductivity.
the critical temperature is for the phase stability? When the phase changes,the energy needed is smaller than the material melton,
