Absorptivity of Small Body using Absorbed Radiation and Temperature Solution

STEP 0: Pre-Calculation Summary
Formula Used
Absorptivity = Absorbed Radiation/([Stefan-BoltZ]*(Temperature^4))
α = Gabs/([Stefan-BoltZ]*(T^4))
This formula uses 1 Constants, 3 Variables
Constants Used
[Stefan-BoltZ] - Stefan-Boltzmann Constant Value Taken As 5.670367E-8
Variables Used
Absorptivity - Absorptivity is the fraction of incident radiation flux absorbed by the body.
Absorbed Radiation - (Measured in Watt per Square Meter) - Absorbed radiation is the amount of radiation energy absorbed by the body per its unit surface area.
Temperature - (Measured in Kelvin) - Temperature is the degree or intensity of heat present in a substance or object.
STEP 1: Convert Input(s) to Base Unit
Absorbed Radiation: 2 Watt per Square Meter --> 2 Watt per Square Meter No Conversion Required
Temperature: 85 Kelvin --> 85 Kelvin No Conversion Required
STEP 2: Evaluate Formula
Substituting Input Values in Formula
α = Gabs/([Stefan-BoltZ]*(T^4)) --> 2/([Stefan-BoltZ]*(85^4))
Evaluating ... ...
α = 0.675683205481613
STEP 3: Convert Result to Output's Unit
0.675683205481613 --> No Conversion Required
FINAL ANSWER
0.675683205481613 0.675683 <-- Absorptivity

What is Kirchhoff law?

The total hemispherical emissivity of a surface at temperature T is equal to its total hemispherical absorptivity for radiation coming from a blackbody at the same temperature. This relation, which greatly simplifies the radiation analysis, was first developed by Gustav Kirchhoff in 1860 and is now called Kirchhoff’s law.
