Abstract

Methods are presented for determining partial and integral thermodynamic quantities for the change in state of water and clay during the course of their interaction. The quantities determined are: free energy, heat and entropy changes. The effect on the magnitude of these quantities of the nature and amount of the exchangeable cations is reported. It is concluded that the magnitude of change in the thermodynamic quantities due to moving the exchangeable cations out of the hexagonal cavities in the oxygen sheets is considerably greater than that due to the parting of the oxygen sheets during the interlayer expansion.
