Hydrogen (H₂) ideal-gas table, per mole

This table gives h̄, ū and s̄° of hydrogen (H₂) as an ideal gas, per kmol, as a function of temperature and measured from 298.15 K and 1 atm (differences between two temperatures are those of any table). Above you can use it interactively (switch units with SI/US, pick the pressure or go to the calculator for any point with step-by-step interpolation). Reference state: values relative to the standard state: h̄ − h̄°, ū − ū° and s̄° − s̄°, all zero at 298.15 K and 1 atm.
