e amount of the emitted heat depends on the absolute temperature of the body. e Stefan-
Boltzmann’s law denes the convection heat transfer phenomenon:
Q AT= σ
4
(
8.6)
where
Q [W] is the rate of heat transfer
A [m
2
] is the surface area of perfectly radiating body
σ
[
W/(m
2
K
4
)] is the Stefan-Boltzmann constant equal to 5.669 × 10
−8
T [K] is the absolute surface temperature
