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.
There is an energy barrier that separates the energy levels of the reactants and products. Energy must be added to the reactants to overcome the energy barrier, which is recovered when products are formed. The energy barrier is known as Ea, the activation energy. The activation energy is distinct from the Î´G, or free energy difference between the reactants and products. The Biology Project.
