What happens to the metals electrical conductivity when the temperature hits up​

Temperature affects metal in numerous ways. A higher temperature increases the electrical resistance of a metal, and a lower temperature reduces it. Heated metal undergoes thermal expansion and increases in volume.

Relation between electrical and thermal conductivity Wiedemann-FRANZ law At a given temperature the thermal and electrical conductivity of metals are proportional, but raising the temperature increase the thermal conductivity while decreasing the electrical conductivity.

firearm identification is the process of analyzing the bullets and cartridge cases left at a crime scene to determine if they came from a particular firearm. marks on the bullets and cartridges may be common to every firearm of that type. these are called class characteristics.
