1 Hydraulic conductivity, a property of a porous material's ability to transmit water. 2  Thermal conductivity, the intensive property of a material that indicates its ability to conduct heat.  Rayleigh conductivity, describing the behavior of apertures concerning the flow of a liquid or gas.
Lower pH corresponds with higher [H + ], while higher pH is associated with lower [H + ]. Electrical conductivity (EC) is a measurement of the dissolved material in an aqueous solution, which relates to the ability of the material to conduct electrical current through it.H is a measure of the acidity of the water or soil based on its hydrogen ion concentration and is mathematically defined as the negative logarithm of the hydrogen ion concentration, or. pH = -log[H + ], where the brackets around the H + symbolize concentration.
