Popis:	Gas chromatographic data for n-hexane and n-heplane on aerosilogel obtained in the temperature interval 55 to 150°C were treated using the method of least squares with orthogonal functions. For this treatment the thermodynamic equation, which assumes that the enthalpy depends on the temperature and that the difference in heat capacities is constant, was used. The differential heats of adsorption as well as the difference in heat capacities ΔaCp of n-hexane and n-heptane in the adsorbed and gaseous state were calculated. It was shown that at the given accuracy of experimental data ΔaCp (for the 5% significance level) differed significantly from zero.
