Question

The energy radiated per unit surface area (across all wavelengths) for a black body with temperature 2200. Use 5.67 x 10-8 for the Stefan-Boltzmann constant.The ____________ describes the power radiated from a black body in terms of its temperature. Specifically, the total energy radiated per unit surface area of a black body across all wavelengths per unit time is proportional to the fourth power of the black body’s thermodynamic temperature

    Answer:

    Stefan-Boltzmann Law describes the power radiated from a black body in terms of its temperature. Specifically, the total energy radiated per unit surface area of a black body across all wavelengths per unit time is proportional to the fourth power of the black body’s thermodynamic temperature

    Explanation:

    So we now know that

    energy per unit area is = zigma x T^4

    From this

    T = temperature in kelvin

    zigma is stefan boltzman constant

    So

    E/A = 5.67 x 10^-8 x (2200)⁴

    = 1.33x 10^6 W/m^2
