SUMMARY
Heat transfer at temperatures exceeding 1000 K is predominantly influenced by radiation, which increases with the fourth power of temperature. However, this is not a universal rule; the significance of radiation versus conduction or convection depends on the specific characteristics of the system, including geometry and surface properties. For metallic conductors, deriving a formula to calculate resistivity based on temperature requires precise knowledge of the conductor's dimensions and resistivity, as well as the relevant boundary conditions.
