Each of the following definitions (a and b) absolute temperature (T) possible and feasible. Describe briefly what each definition differs from the the official definition (adopted in 1954 by the International Committee of weights and measures), and explain why each of these definitions has General application. The official definition is: T= 1/(n*R) lim PV where n is the number of moles of gas, V - volume, P - pressure and R is a constant chosen so that T=273,16° C at the triple point of water. a) T = 100*(L-Lf)/(Lb - Lf) where L is the height of a column of mercury of constant cross section at temperature T, Lb and Lf is the height of the same column at the points of phase transitions (boiling and solidification, respectively) of the water saturated with air under a pressure of one standard atmosphere (1,01325*10^6 dyn/cm2). b) T=PV/nR, where V is the volume at one atmosphere of pressure n moles of pure oxygen with the isotope composition found in the earth´s atmosphere. One mole is defined as the amount of oxygen (31.9988 g approximately), which contains the same
