Question

Stefan-Boltzman’s law is an equation that allows you to calculate __________, if you just know the temperature of the body.

Answer 1

Answer:

the total radiant heat power

Explanation:

The Stefan-Boltzmann law states that the total radiant heat power emitted from a surface is proportional to the fourth power of its absolute temperature.

$E=\sigma T^{4}$

where E is the power from a unit area, T is the absolute temperature and the Greek letter sigma (σ) representing the constant of proportionality, called the Stefan-Boltzmann constant. In SI units, this constant has the value $5.670374419 * 10^{-8} \frac{W}{m^{2} K^{4} }$.

The law applies only to blackbodies, theoretical surfaces that absorb all incident heat radiation.
