There are three modes of heat transfer: conduction, convection, and radiation. Each has an empirical law that relates the rate of heat transfer, q (W), to a temperature difference driving force. The rate law for radiation is known as the Stefan-Boltzmann Law. For a black-body, the Stefan-Boltzmann Law is: q=0A(TT) - In this equation, q is the rate of heat transfer (W), σ is the Stefan-Boltzmann constant, A is the area (m²), T is the temperature of the material, and Ter is the temperature of the surroundings. surr Value of SB Constant in Other Units Report the numerical value of the Stefan-Boltzmann constant for units of cal/(h·yd 2.R4)? i
