Re: exponential cooling



Does the exponential law of cooling apply to the radiational mechanism,
for example, to a very hot brick suspended in very good vacuum?
Ludwik Kowalski

I recall this mechanism goes as the difference between T^4 of the brick and
T^4 of 'its surroundings'. Wouldn't everything that goes as some
difference be exponential? It seems to me like the time constant might be
affected by the power of T involved, but the cooling would be exponential.
