Abstract
LANDSBERG1,2 has raised the question of the correct definition of temperature in relativistic thermodynamics. He advances2 a general case against the orthodox transformation of temperature by considering the case of two systems, possessing equal proper temperatures, T0, and in relative motion. Then observers moving with the two systems will each judge the temperature of the other system to be lower than that of the system with which he is moving. If the usual relation exists between temperature difference and heat flow, both proper temperatures should fall, a conclusion Landsberg finds unacceptable. The argument is not, however, completely convincing, and Williams3 has pointed out that the direction of energy flow between two systems is, in general, dependent on the frame of reference in which the flow is observed.
