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.
exothermic reacticon-a chemical reaction in which energy is released to the surroundings as heat endothermic reaction-a chemical reaction in which more energy is needed to br â¦ eak the bonds in the reactants than is given off by forming bonds in the products.here is a net loss of energy from the reactants.   However, exothermic reactions also need a lit â¦ tle energy to get started, but this is less than the eventual amount given out.   An endothermic reaction takes in energy, also usually from the surroundings.
