Swelling. Swelling (edema) is a build-up of water in the tissues. This can be caused by retaining salt and water due to medicines or heart, liver, or kidney failure. It can sometimes be due to poor nutrition, pelvic tumors, or a blockage in the veins or lymph system.
Reactance, denoted X, is a form of opposition that electronic components exhibit to the passage of alternating current (alternating current) because of capacitance or inductance. In some respects, reactance is like an AC counterpart of DC (direct current) resistance.
Thermodynamic stability applies to a particular system. The reactivity of a chemical substance is a description of how it might react across a variety of potential chemical systems and, for a given system, how fast such a reaction could proceed.his may be a dynamic equilibrium, where individual atoms or molecules change form, but their overall number in a particular form is conserved. This type of chemical thermodynamic equilibrium will persist indefinitely unless the system is changed.
