      Abstract:

      Calorimetrically measured heats of solution of eleven hydrocarbon   gases into water are reported at 15 and 25°C. Gases studied are   methane, ethane, propane, n-butane, 2-methylpropane,   2,2-dimethylpropane, cyclopropane, ethene, propene, 1-butene, and   ethyne. These values in combination with previous results are   used to derive heat capacity changes at 25°C. Comparison of   enthalpy and heat capacity values with those from other studies   shows satisfactory agreement. Correlation of the heat capacity   change with the number of water molecules in the first solvation   shell of the solute suggests that the observed heat capacity   changes are primarily due to changes in the water molecules in   this solvent shell.
