Abstract: This SI version of the fifth edition has bee prepared for those who want to use the joule in thermodynamic calculations and SI units more completely in other sections. The calorie has been replaced by the joule (1 cal = 4.184 J), the torr has been replaced by the pascal (1 torr = 133.322 Pa), and the gauss has been replaced by the tesla (1 G = 10-4 T). In calculations using other quantities in SI units, pressures are expressed in pascals. This has real advantages in calculations because the SI system is coherent; that is, no additional numerical factors appear in equations relating different physical quantities.
Thermodynamics deals with relationships between properties of systems at equilibrium and with differences in properties between various equilibrium states. It has nothing to do with time. Even so, it is one of the most powerful tools of physical chemistry.
