Heat capacities of H₂, He⁴, Ar and N₂ adsorbed in zeolite are measured in the temperature range between 2 K and 20 K. Results show no sign of peaks or jumps characteristic of the phase transition of either the first kind or the second kind in the case of bulk samples. Dependence on the amount of adsorption, cation replacement, and on the atoms or molecules adsorbed are reported.
