Stefan's Law

Stefan's Law, a fundamental principle in thermodynamics and radiative heat transfer, describes the power radiated from a black body per unit area. Named after Austrian physicist Josef Stefan, this law states that the power radiated is directly proportional to the fourth power of the black body's absolute temperature. Expressed mathematically as P = σAT^4, where P is the power emitted, σ is the Stefan-Boltzmann constant, A is the surface area, and T is the absolute temperature, Stefan's Law has wide-ranging applications in astrophysics, engineering, and climate science, offering insights into energy transfer mechanisms in various systems.
