What Is Diffusion? Chemistry Definition - ThoughtCo

Diffusion is a natural mass transport mechanism that moves matter from area of high concentration to those of low concentration. Diffusion is a natural mass transport mechanism that moves matter from area of high concentration to those of low concentration. Science Photo Library Ltd / Getty Images by Anne Marie Helmenstine, Ph.D. Updated June 13, 2017 DIFFUSION DEFINITION Diffusion is the movement of a fluid from an area of higher concentration to an area of lower concentration. Diffusion is a result of the kinetic properties of particles of matter. The particles will mix until they are evenly distributed. Diffusion may also be thought of as movement of particles down a concentration gradient. The term "diffusion" comes from the Latin word diffundere, which means "to spread out". DIFFUSION EXAMPLES H2S(g) in a test tube will slowly diffuse into the air of a lab until equilibrium is reached. Food coloring in water diffuses until it's evenly distributed throughout the liquid. Perfume diffuses throughout an entire room. Adding a dot of dye to gelatin is a good example. The color will slowly diffuse throughout the gel. Note, however, most of the common examples of diffusion also illustrate other mass transport processes. For example, when perfume is smelled across a room, air currents or convection are more of a factor than diffusion. Convection also plays a large role in the dispersion of food coloring in water.

Diethyl malonate, also known as DEM, is the diethyl ester of malonic acid. It occurs naturally in grapes and strawberries as a colourless liquid with an apple-like odour, and is used in perfumes. It is also used to synthesize other compounds such as barbiturates, artificial flavourings, vitamin B1, and vitamin B6.

Wednesday, September 6, 2017 Cortisol is a steroid hormone, in the glucocorticoid class of hormones. When used as a medication, it is known as hydrocortisone. It is produced in humans by the zona fasciculata of the adrenal cortex within the adrenal gland. Wikipedia Formula: C21H30O5 Molar mass: 362.46 g/mol CAS ID: 50-23-7 ChEBI ID: 17650 ChemSpider ID: 5551 PubChem CID: 5754 People also search for: Cortisone, Adrenocorticotropic hormone, MORE What is cortisol? Cortisol is a steroid hormone, one of the glucocorticoids, made in the cortex of the adrenal glands and then released into the blood, which transports it all round the body. Almost every cell contains receptors for cortisol and so cortisol can have lots of different actions depending on which sort of cells it is acting upon. These effects include controlling the body’s blood sugar levels and thus regulating metabolism, acting as an anti-inflammatory, influencing memory formation, controlling salt and water balance, influencing blood pressure and helping development of the foetus. In many species cortisol is also responsible for triggering the processes involved in giving birth. A similar version of this hormone, known as corticosterone, is produced by rodents, birds and reptiles. Posted by Oscar del Rosario at 12:40 AM Email This BlogThis!
