Abruzzo (US: / ɑː ˈ b r uː t s oʊ, ə ˈ-/, [3] [4] UK: / æ ˈ b r ʊ t s oʊ /; [5] Italian:; Abruzzese Neapolitan: Abbrùzze [abˈbruttsə], Abbrìzze [abˈbrittsə] or Abbrèzze [abˈbrɛttsə]; Aquilano: Abbrùzzu), historically known as Abruzzi, is a region of Southern Italy with an area of 10,763 square km (4,156 sq mi) and a ...
The constants listed here are known values of physical constants expressed in SI units; that is, physical quantities that are generally believed to be universal in nature and thus are independent of the unit system in which they are measured. Many of these are redundant, in the sense that they obey a known relationship with other physical ...
This glossary of chemistry terms is a list of terms and definitions relevant to chemistry, including chemical laws, diagrams and formulae, laboratory tools, glassware, and equipment. Chemistry is a physical science concerned with the composition, structure, and properties of matter , as well as the changes it undergoes during chemical reactions ...
A definition of "matter" based on its physical and chemical structure is: matter is made up of atoms. [17] Such atomic matter is also sometimes termed ordinary matter. As an example, deoxyribonucleic acid molecules (DNA) are matter under this definition because they are made of atoms.
Chemistry is the scientific study of the properties and behavior of matter. [1] It is a physical science within the natural sciences that studies the chemical elements that make up matter and compounds made of atoms, molecules and ions: their composition, structure, properties, behavior and the changes they undergo during reactions with other substances.
Pizzelle are a typical Abruzzo sweet. Abruzzo's sweets are well-known: Confetti di Sulmona: [57] sugar-coated almonds from Sulmona; Torrone Nurzia: chocolate nougat from L'Aquila; Parrozzo: a cake-like treat made from crushed almonds and coated in chocolate; Pizzelle (also known as ferratelle): a waffle cookie, often flavored with anise [23]
Licorice of Atri has been cultivated in Abruzzo since Roman times, and in the Middle Ages the friars already used it by extracting the juice; the region Abruzzo is after Calabria for licorice production. [4] Famous in Italy are the licorice trunks of the candy Tabù produced by the company R. De Rosa founded in 1836 in Atri in Abruzzo. [5]
Joseph Priestley and Antoine Lavoisier discover a new gas called oxygen, discrediting the basic theory of chemistry at the time, creating the basis for the modern science of chemistry, and prompting chemists all over the world to look for more new elements; Humphry Davy introduces audiences to nitrous oxide ("laughing gas") and uses electricity to search for new chemical elements.
