Question

What is Stefan law ? Give example​

Answer 1

Answer:

If sun is emitting energy 1. 5×103cal/s from each of its cm2 surface . If Stefan's constant is 5. 7×10−8J/s1m2K4 then estimate the surface temperature of the sun .

Answer 2

Stefan-Boltzmann law, statement that the total radiant heat power emitted from a surface is proportional to the fourth power of its absolute temperature. ... The law applies only to blackbodies, theoretical surfaces that absorb all incident heat radiation.

The Stefan-Boltzmann law, also known as Stefan's Law, is a law that expresses the total power per unit surface area (otherwise known as the intensity) that is radiated by an object, often taken to be a blackbody. The formula used to determine at what wavelength the power peaks at is Wien's Law.
