From the power-time curves, the CMC and $\Delta H_{\mathrm{m}}^{\uptheta}$ values were obtained. The corresponding values of $\Delta G_{\mathrm{m}}^{\uptheta}$ and $\Delta S_{\mathrm{m}}^{\uptheta}$ were also calculated. The relationships of the CMC with the carbon number of the alcohol, the concentration of alcohol, and the temperature, along with the thermodynamic functions, are discussed.
