Temperature of work done on the work reservoir, and the first law of thermodynamics. The amounts of energy transferred as heat respectively from reservoir 1 and from reservoir 2 may then be denoted respectively and . Then the absolute or thermodynamic temperatures, and , of the reservoirs are defined so that to be such that Kelvin's original work postulating absolute temperature was published in 1848. It was based on the work of Carnot, before the formulation of the first law of thermodynamics. Kelvin wrote in his 1848 paper that his scale was absolute in the sense that it was defined "independently
Planck temperature scale Planck temperature scale The Planck temperature scale is an absolute temperature scale using natural units. On this scale, 0 is absolute zero, and 1 is the Planck temperature. Quantum Theory states that the Planck temperature is the hottest possible temperature. The symbol used for this scale is "T". The freezing/melting point of water on this scale would be written 1.928 × 10"T". A way of expressing temperatures in more familiar sized units is to use centimicroyocto plank temperatures (cµy"T"). The freezing point of water is 1.928 × 10"T". By simply moving the decimal point 32 places to the right, you
