The Entropy of Radiation

Nature volume 74, pages iiiv (11 October 1906) | Download Citation



A QUANTITY of heat Q is transferred by radiation from a body the surface of which is at temperature T1 to a body the surface of which is at a lower temperature T2. From this cause alone the former body loses a quantity of entropy Q/T1, while the latter gains a quantity of entropy Q/T2. The net gain of entropy of the bodies arising from the transaction is Q(i/T2_ i/T1). Where and how does this gain take place?
