Stefan-Boltzmann Law
The Stefan-Boltzmann Law states that the total amount of energy emitted by a black body—an idealized object that absorbs all radiation—depends on its temperature. Specifically, the energy output increases dramatically as the temperature rises, following the formula \(E = \sigma T^4\), where \(E\) is the energy emitted per unit area, \(T\) is the absolute temperature in Kelvin, and \(\sigma\) is a constant. This means that if you double the temperature, the energy emitted increases by a factor of 16, illustrating how heat affects radiation and is crucial in fields like astronomy and climate science.

The Stefan-Boltzmann Law states that the total energy radiated by a perfect black body is proportional to the fourth power of its absolute temperature. In simpler terms, as an object gets hotter, it emits significantly more energy. For example, if you double the temperature of an object, it will radiate 16 times more energy. This law helps explain why the sun, being extremely hot, emits so much energy, and why even small increases in temperature can lead to a big jump in energy output, which is crucial in fields like astronomy, climatology, and engineering.
