By the Stefan-Boltzmann Law, the flux emitted by a blackbody is proportional to the (*) fourth power of this quantity.
By the free-electron model, the resistivity of a metal is proportional to the square root of this quantity. Wien's Law states that the peak wavelength for blackbody emission is proportional to one over this quantity. By the Stefan-Boltzmann Law, the flux emitted by a blackbody is proportional to the (*) fourth power of this quantity. The rate of heat transfer is proportional to the gradient of this quantity, which is related to the average kinetic energy of a system's molecules. For 10 points, name this quantity measured in scales named after Kelvin and Fahrenheit.
By the free-electron model, the resistivity of a metal is proportional to the square root of this quantity.
