5.6.162 - Stefan-Boltzmann law

Be able to use the Stefan-Boltzmann law equation L = σAT4 for black body radiators.

Use - stefan-boltzmann law to connect the rule to the data and decision in the question.

This matters because - stefan-boltzmann law determines what can be inferred or chosen; begin with the stated conditions and keep the conclusion tied to the evidence.

Example: apply - stefan-boltzmann law to one small, clearly defined case, show the key step or comparison, and explain the result in words.

Boundary: - Stefan-Boltzmann law is not a universal recommendation. Check the syllabus scope, assumptions, units and the limits of the evidence before generalising.
