Explanation:
The Stefan–Boltzmann Law explains how much energy an object emits based on its temperature. It applies to a perfect blackbody, which is an ideal object that absorbs all the energy it receives and re-emits it as heat or light.
According to this law, as the temperature of an object increases, the amount of energy it radiates increases dramatically. Specifically, if the temperature of the object doubles, the energy it emits increases sixteen times. This shows that even a small rise in temperature leads to a large increase in the energy output.
This principle helps scientists understand why stars shine so brightly, how the Earth radiates heat into space, and how thermal imaging works. It is a key concept in physics, astronomy, and climate science.
