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 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.
Thermal conductivity temperature to an object that has a?
The thermal conductivity temperature of different objects vary from one object to another. When the two objects are placed together, there will be a change in temperature through heat conduction.
How does thermal conductivity change with temperature?
Thermal conductivity generally increases with temperature. This means that as temperature rises, materials are better able to conduct heat.
What is the relationship between specific heat and thermal conductivity in materials?
The relationship between specific heat and thermal conductivity in materials is that specific heat measures the amount of heat needed to raise the temperature of a material, while thermal conductivity measures how well a material can transfer heat. Materials with high specific heat can absorb more heat without a large temperature change, while materials with high thermal conductivity can transfer heat quickly.

What combination of factors is most suitable for increasing the electrical conductivity of metals?
Resistivity is a constant for any particular material, and independent of that material's physical dimensions or shape. However, it does vary with temperature which is why resistivity is always quoted at a particular temperature. Variations in resistivity due to temperature change is the reason that the resistance of a material varies with temperature. In SI, resistivity is expressed in ohm metres.
How does thermal conductivity change with temperature?

What is the relationship between specific heat and thermal conductivity in materials?
The relationship between specific heat and thermal conductivity in materials is that specific heat measures the amount of heat needed to raise the temperature of a material, while thermal conductivity measures how well a material can transfer heat. Materials with high specific heat can absorb more heat without a large temperature change, while materials with high thermal conductivity can transfer heat quickly.
What is the change in conductivity as the concentration of the NaCl solution was increased by the addition of NaCl drops?
The electrical conductivity of the solution will be higher if the concentration of NaCl increase.
What happens to thermal conductivity of a wall if its thickness double?
If the thickness of a wall is doubled, the thermal conductivity remains the same unless the material composition or other properties of the wall are altered. Thermal conductivity is a material property that is independent of the dimensions of the material. So, as long as the material itself doesn't change, doubling the thickness will not alter the thermal conductivity.
Is electrical conductivity a chemical change?
No, electrical conductivity is a physical property that depends on the ability of a material to carry an electric current. It is not a chemical change because the chemical composition of the substance remains the same.
Can temperature effect the conductivity of material?
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 .
In a graph showing temperature change of a material over time temperature change is the .?
dependent variable
How does the conductivity of metal change with temperature?
The conductivity of metal generally increases with temperature. This is because as temperature rises, the atoms in the metal vibrate more vigorously, allowing electrons to move more freely and carry electrical charge more effectively.
