Question #1
Stefan-Boltzmann Law states that the total radiant heat energy emitted from a perfectly black body is proportional to:
A. T^2
B. T^4
C. T^3
D. T

Correct Answer: Option B


Explanation:
The Stefan-Boltzmann law dictates that the total energy radiated per unit surface area of a black body across all wavelengths per unit time (Emissive Power, E) is strictly directly proportional to the fourth power of the black body's thermodynamic (absolute) temperature. E = sigma * T^4, where sigma is the Stefan-Boltzmann constant.
