    Plant water relations overview We use the term water potential (Ψw) to describe the chemical potential of water, and our understanding of diffusion of water depends on our understanding of how various factors (such as temperature, pressure, presence of dissolved solutes) affect the water potential in various parts of a system. Since diffusion of a substance tends to occur downward along a chemical potential or free energy gradient, it also is important to understand how such gradients are established. By...

    Consider a cylindrical capacitor like that shown in Fig. 24.6. Let d = rb − ra be the spacing between the inner and outer conductors. (a) Let the radii of the two conductors be only slightly different, so that d << ra. Show that the result derived in Example 24.4 (Section 24.1) for the capacitance of a cylindrical capacitor then reduces to Eq. (24.2), the equation for the capacitance of a parallel-plate capacitor, with A being the surface area of...
