Heat capacity varies at different temperatures. At room temperature, the highest heat capacities known are:
hydrogen gas -- 14.3 J/K/g water vapour -- 7.3 J/K/g helium gas -- 4.3 J/K/g liquid water -- 4.2 J/K/gThis was calculated from data in the CRC Handbook of Chemistry and Physics -- thermodynamics table in section D. I do not know where the values are tabulated directly.
These are constant pressure heat capacities compared on an equal mass basis.
