Explain the formula of the Stefan law.

STEFAN'S LAW:

P = σ AT4

Here:

P = Power radiated into W (J/s)

σ = Stefan's Constant 5.67 x 10-8W m-2K-4

A = Surface area of body (m2)

T = Temperature of body (K)

Thus the power radiated is proportional to T4 for an identical body that describes why the region under the black body curves (the entirety energy) increases too much for a relatively small raise in temperature.
