"Phlogistian" Natural Recordings by Native Speakers
A chemical term that has largely fallen out of use!Phlogiston was a hypothetical chemical substance which was hypothesized to be an element in many gases and elements, and was one of the first substance that was supposed to be found in all flammable materials and combined with oxygen to form fire.In the 17th and 18th centuries, chemists believed that phlogiston was released from a body when it burned, and that it was a matter of opening a means for the phlogiston to escape. Due to the work of Antoine Lavoisier, in the late 18th century, the concept of phlogiston fell out of favor with the discovery of oxygen, and it is now not considered to be a chemical substance, but rather a hypothetical concept that has been largely discredited.
A phlegmon is a non-tubercular, inflammatory process that can occur in any tissue or organ of the body, especially in the skin, causing it to become swollen and painful. It is characterized by a localized collection of pus in the tissue, often resulting in a large, painful mass.
Phlegmonous refers to a type of inflammation that forms a thick, walled-off abscess or pocket of pus, typically in the tissue or fascia of the body. This is often seen in cases of severe infections, such as gangrene, gas gangrene, or paronychia. Phlegmonous inflammation can occur in various parts of the body, including the skin, soft tissue, and organs, and can be life-threatening if left untreated.
The Phlegraean Fields (also known as Phlegraean Islands) refers to a large volcanic caldera system located in the Bay of Naples, Italy. It's a unique and complex geological area with several volcanoes, including Mount Terra Murata and the famous Mount Vesuvius, which is one of the most famous volcanoes in the world.The word "Phlegraean" itself comes from the Greek word "Phlegrae", which means "burning" or "fiery". This refers to the volcanic activity that has shaped this region over thousands of years.The Phlegraean Fields are also home to several hot springs, lakes, and fumaroles (steam vents), which are remnants of the volcanic activity that has shaped the area. The region is of great scientific interest due to its unique geology and ongoing volcanic processes.
Phlethysmography is a term used to describe the measurement of changes in blood volume or blood pressure in the body. It is often used in medical research and clinical settings to assess blood flow, congestion, and cardiac function. The term is derived from the Greek words "phlethys" meaning blood and "graphy" meaning writing or measurement.
Phleum is a type of grass commonly known as rye grass. It is a genus of grasses in the family Poaceae. Phleum is native to Europe and Asia, and is widely cultivated for its leaves and seeds, which are used as fodder for livestock. The seeds of the phleum plant are also edible and are used as a food source.
The phloem (also known as the "bast") is a tissue in plants that is composed of sieve cells and is responsible for transporting organic nutrients, sugars, and other chemical signals produced by photosynthesis from the leaves (where they are produced) to the rest of the plant, including the woody stem, roots, and other aerial parts.
Phloeophagy is a rare and obscure term that refers to the habit of eating or devouring resin. In other words, it means to feed on resin, which is a sticky substance produced by certain plants as a defense mechanism.
Phlogisticate is a verb that means to treat with or as if with phlogiston, a hypothetical substance formerly believed to be a necessary component of all combustible materials. In modern chemistry, the term is now used more broadly to mean to treat or analyze something as if it contained phlogiston, often in a metaphorical or humorous sense.
Phlogiston is a hypothetical substance that was once believed to be present in all combustible materials and to be released during combustion. The concept of phlogiston was developed by Johann Joachim Becher and his disciple, Georg Ernst Stahl, in the late 17th century. According to this theory, phlogiston was a material substance that was contained within combustible materials and was released during combustion, leaving behind the calx (a type of oxide). The idea was that air was necessary to combustion not because it supplied oxygen, but because it helped to carry away the phlogiston released during combustion. The theory of phlogiston was abandoned in the 18th century with the development of the theory of combustion by Antoine Lavoisier, who showed that the essential substance released during combustion is actually oxygen, not phlogiston.
The word "phlogogenous" refers to something that produces or is capable of producing flammable substances. This term is typically used in a scientific or technical context, particularly in chemistry and physics.
Phlogopite is a type of mineral that is a member of the mica group. It is a silicate mineral with the chemical formula KMg3(AlSi3O10)(F,OH)2. It is typically found in metamorphic and igneous rocks and is often used as a gemstone or in abrasive materials.
Phlogosis is a rare or obsolete term that refers to a hypothetical inflammation of the skin or mucous membranes, characterized by an abnormal or excessive production of phosphoric acid. It is no longer a commonly used medical term and has been largely replaced by more specific and accurate diagnoses.
Phlogotic refers to a theoretical concept in Renaissance chemistry which suggests that all materials contain a fundamental substance called "phlogiston", which is released during combustion. In essence, phlogotic theory claimed that combustible materials, like wood or coal, contain this phlogiston within themselves, which is set free when they burn. Unfortunately, phlogiston was later found to be a fictional concept with no scientific basis.
Phlomis is a type of flowering plant, commonly known as Jerusalem Sage or Trahira. It is a perennial shrub native to the Mediterranean region and is often used in landscaping and gardening for its attractive foliage and fragrant flowers.
