Self-cleaning, often with temperatures that go over 1000Â°, is a particular problem. The elements and the oven just get so hot â much, much hotter than the 350Â° to 500Â° range of normal baking â that sometimes fuses pop and control panels burn out. Manufacturers, Adam implied, know this and they understand that self-cleaning cycles are a problem. But, he said, customers demand self-cleaning options.
Opacity Opacity is the measure of impenetrability to electromagnetic or other kinds of radiation, especially visible light. In radiative transfer, it describes the absorption and scattering of radiation in a medium, such as a plasma, dielectric, shielding material, glass, etc.
The noun brevity means shortness or conciseness. If you give a report on agriculture in the northern hemisphere in 3 minutes, you have done it with incredible brevity. Brevity comes from brevis, which means brief in Latin. You can use brevity for things that are literally short, like the brevity of an elevator meeting, or the quality of fleetingness, like the brevity of youth. Brevity is also a style of speaking or writing with economy.
