Because the water dissolving the gorges drains to the subsurface, the gorges are not integrated into a valley system.
Surprisingly, anhydrous Form I was found to be the thermodynamically most stable crystal form in water, dissolving six times slower than the dihydrate, a difference that correlates well with the rank order of aqueous solubility.
Under these conditions the dissolved salt mixture evaporates concentrating the solution and precipitating one of the two salts, and the solid salt mixture absorbs water dissolving the salts until equilibrium is reached.
The addition of water dissolving the water-soluble surfactant to oil dissolving the oil-soluble surfactant, direct emulsification method, produced by far large droplets because of a rather high interfacial tension.
For a target cyclohexane-in-water emulsion using a pair of polyoxyethylene nonylphenyl ether surfactants with a specified HLB and water volume fraction, fine droplets could form only if water dissolving the water-soluble surfactant was added to the oil dissolving the oil-soluble surfactant.
This is attributed to the greater amount of water dissolving larger oligomers at higher flow rates and the rapid removal of dissolved oligomers from the reactor by the higher flow rate before the oligomers can hydrolyze further [ 65].
