The Stefan-Boltzmann Law

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

P = σ * A * T⁴

Where σ is the Stefan-Boltzmann constant (5.670373 × 10⁻⁸ W/m²K⁴).
