The study of the absorption or release of heat during a chemical reaction. thermodynamic stability. The condition of a system being in its lowest energy state with its environment (equilibrium). thermodynamics. The study of the effects of changing temperature, volume or pressure (or work, heat, and energy) on a macroscopic scale.
Dry lab. A dry lab is a laboratory where the nature of the experiments does not involve significant risk. This is in contrast to a wet lab where it is necessary to handle various types of chemicals and biological hazards. An example of a dry lab is one where computational or applied mathematical analyses are done on a computer-generated model ...
Dye. Drying colored cloth. Chemical structure of indigo dye, the blue coloration of blue jeans. Although once extracted from plants, indigo dye is now almost exclusively synthesized industrially. [1] A dye is a colored substance that chemically bonds to the substrate to which it is being applied. This distinguishes dyes from pigments which do ...
Fire extinguisher. A stored-pressure fire extinguisher made by Amerex. A fire extinguisher is a handheld active fire protection device usually filled with a dry or wet chemical used to extinguish or control small fires, often in emergencies. It is not intended for use on an out-of-control fire, such as one which has reached the ceiling ...
Gypsum concrete is a building material used as a floor underlay [43] used in wood-frame and concrete construction for fire ratings, [43] sound reduction, [43] radiant heating, [44] and floor leveling. It is a mixture of gypsum, Portland cement, and sand. [43] One of its advantages is the lightweight nature.
Scientific terminology is the part of the language that is used by scientists in the context of their professional activities. While studying nature, scientists often encounter or create new material or immaterial objects and concepts and are compelled to name them. Many of those names are known only to professionals.
Spray drying is a method of forming a dry powder from a liquid or slurry by rapidly drying with a hot gas. This is the preferred method of drying of many thermally-sensitive materials such as foods and pharmaceuticals, [1] or materials which may require extremely consistent, fine particle size.
Volatile organic compounds ( VOCs) are organic compounds that have a high vapor pressure at room temperature. [1] High vapor pressure correlates with a low boiling point, which relates to the number of the sample's molecules in the surrounding air, a trait known as volatility. [2]
