Molar heat capacities (Cp,m) of the room-temperature ionic liquid (IL) 1-propyl-3-methylimidazolium glutamic acid salt ([C3mim][Glu]) were measured with a high-precision automated adiabatic calorimeter (AC) in the temperature range of T = (85 to 360) K. A glass transition was observed at 239.861 K. The enthalpy and entropy of the glass transition were determined to be 2.87 kJ*mol-1 and 11.97 J*K-1*mol-1, respectively. Two polynomial equations of molar heat capacity as a function of the temperature were fitted before and after the glass transition. The thermodynamic functions (HT - H298.15) and (ST - S298.15) were derived from the molar heat capacity data in the temperature range of T = (85 to 360) K with an interval of 5 K.
