What is Stefan Boltzmann law?

Answer 1

The Stefan-Boltzmann law is #L=AsigmaT^4#, where:

This law is used to find the luminosity (the rate of energy released), for an object given its surface temperature. This law assumes the body acts as a black-body radiator (an object that emits energy from the entire EM spectrum)

For a given object with a constant surface area, the Stefan-Boltzmann law says that luminosity is proportional to the temperature raised to the fourth power.

The Stefan-Boltzmann law states that the total energy radiated per unit surface area of a black body is directly proportional to the fourth power of the body's absolute temperature. Mathematically, it is expressed as E = σT^4, where E is the total energy radiated per unit area (in watts per square meter), σ is the Stefan-Boltzmann constant (5.67 x 10^-8 W/m^2K^4), and T is the absolute temperature of the body in Kelvin.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
