What is the Stefan Boltzmann constant?

Answer 1

#5.670367 × 10^-8 kg s^-3 K^-4#

Stefan Boltzmann constant is usually denoted by #sigma# and is the constant of proportionality in Stefan Boltzmann's law.

Here, #k# is the Boltzmann constant, #h# is Planck's constant, and #c# is the speed of light in a vacuum.

The Stefan-Boltzmann constant (σ) is a physical constant that relates the total energy radiated per unit surface area of a black body to its temperature. It has a value of approximately 5.67 × 10^-8 watts per square meter per Kelvin to the fourth power (W⋅m^-2⋅K^-4).

Xavier Adame

The Stefan-Boltzmann constant, denoted by σ, is a physical constant that relates the energy radiated by a black body to its temperature. It is named after Josef Stefan and Ludwig Boltzmann. The value of the Stefan-Boltzmann constant is approximately (5.67 \times 10^{-8}) watts per square meter per kelvin to the fourth power, or (5.67 \times 10^{-8} , \text{W m}^{-2} , \text{K}^{-4}). It appears in the Stefan-Boltzmann law, which states that the total energy radiated per unit surface area of a black body is proportional to the fourth power of the body's absolute temperature.

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.
