... The Kelvin scale of hotness, T, is proportional to the ideal-gas scale of temperature. Write kT = PV/N. The unit of the Kelvin scale, K, is defined such that the triple point of pure water is T = 273.16 K exactly. Experimental value: k = 1.38x10-23 J/K. k is the conversion factor between the two sca ...
