  1. Absolute Temperature A temperature scale is an absolute temperature scale if and only if , where and are the heats exchanged by a Carnot cycle operating between reservoirs at temperatures T1 and T2. T2 T1 We showed: Energy efficiency of the Carnot cycle is independent of the working substance. Definition of temperature independent of any material property Measurement of Temperature ratio

  2. As discussed earlier, unique temperature scale requires fixed point or Tfix =Ttripel=273.16K Kelvin-scale: It turns out: empirical gas temperature proportional to thermodynamic Temperature T Why Because: Calculation of efficiency of Carnot cycle based on yields a=1 With

  3. From definition of thermodynamic temperature If any absolute temperature is positive all other absolute temperatures are positive there is an absolute zero of thermodynamic temperature when the rejected heat 0 however T=0 can never be reached, because this would violate the Kelvin statement
