Gay-Lussac's lawGay-Lussac's law usually refers to Joseph-Louis Gay-Lussac's law of combining volumes of gases, discovered in 1808 and published in 1809. However, it sometimes refers to the proportionality of the volume of a gas to its absolute temperature at constant pressure. The latter law was published by Gay-Lussac in 1802, but in the article in which he described his work, he cited earlier unpublished work from the 1780s by Jacques Charles. Consequently, the volume-temperature proportionality is usually known as Charles's Law.
Charles's lawCharles's law (also known as the law of volumes) is an experimental gas law that describes how gases tend to expand when heated. A modern statement of Charles's law is: When the pressure on a sample of a dry gas is held constant, the Kelvin temperature and the volume will be in direct proportion. This relationship of direct proportion can be written as: So this means: where: V is the volume of the gas, T is the temperature of the gas (measured in kelvins), and k is a non-zero constant.
Le MondeLe Monde (lə mɔ̃d; The World) is a French daily afternoon newspaper. It is the main publication of Le Monde Group and reported an average circulation of 479,243 copies per issue in 2022, about 40,000 of which were sold abroad. It has had its own website since 19 December 1995 and is often the only French newspaper easily obtainable in non-French-speaking countries. It should not be confused with the monthly publication Le Monde diplomatique, of which Le Monde has 51% ownership, but which is editorially independent.
AsparagineAsparagine (symbol Asn or N) is an α-amino acid that is used in the biosynthesis of proteins. It contains an α-amino group (which is in the protonated −NH form under biological conditions), an α-carboxylic acid group (which is in the deprotonated −COO− form under biological conditions), and a side chain carboxamide, classifying it as a polar (at physiological pH), aliphatic amino acid. It is non-essential in humans, meaning the body can synthesize it. It is encoded by the codons AAU and AAC.
Ski resortA ski resort is a resort developed for skiing, snowboarding, and other winter sports. In Europe, most ski resorts are towns or villages in or adjacent to a ski area – a mountainous area with pistes (ski trails) and a ski lift system. In North America, it is more common for ski areas to exist well away from towns, so ski resorts usually are destination resorts, often purpose-built and self-contained, where skiing is the main activity. Ski resorts are located on both Northern and Southern Hemispheres on all continents except Antarctica.
Notre-Dame de ParisNotre-Dame de Paris (nɔtʁ(ə) dam də paʁi; meaning "Our Lady of Paris"), referred to simply as Notre-Dame, is a medieval Catholic cathedral on the Île de la Cité (an island in the Seine River), in the 4th arrondissement of Paris, France. The cathedral, dedicated to the Virgin Mary, is considered one of the finest examples of French Gothic architecture. Several attributes set it apart from the earlier Romanesque style, particularly its pioneering use of the rib vault and flying buttress, its enormous and colourful rose windows, and the naturalism and abundance of its sculptural decoration.
Evolution of languagesThe evolution of languages or history of language includes the evolution, divergence and development of languages throughout time, as reconstructed based on glottochronology, comparative linguistics, written records and other historical linguistics techniques. The origin of language is a hotly contested topic, with some languages tentatively traced back to the Paleolithic. However, archaeological and written records extend the history of language into ancient times and the Neolithic.
