chlorofluorocarbons chlorofluorocarbons
chlorofluorocarbons (CFCs), organic compounds that contain carbon, chlorine, and fluorine atoms. CFCs are highly effective refrigerants that were developed in response to the pressing need to eliminate toxic and flammable substances, such as sulfur dioxide and ammonia, in refrigeration units and...

sulfur dioxide sulfur dioxide
sulfur dioxide chemical compound, SO 2 , a colorless gas with a pungent, suffocating odor. It is readily soluble in cold water, sparingly soluble in hot water, and soluble in alcohol, acetic acid, and sulfuric acid. It is corrosive to organic materials and dissolves in water to form sulfurous acid,... Read more
silica gel silica gel
silica gel chemical compound. It is a colloidal form of silica , and usually resembles coarse white sand. It may be prepared by partial dehydration of meta silicic acid, H 2 SiO 3 . Because it has many tiny pores, it has great adsorptive power. It is used as a drying agent, as a catalyst or... Read more
aerogel aerogel
aerogel any of a group of extremely light and porous solid materials; the lightest is less than four times as dense as dry air. Aerogels are produced from certain gels (see colloid ) by heating the gel under pressure, which causes the liquid in the gel to become supercritical (in a state between a... Read more
Refrigerants Refrigerants
Refrigerator Background Prior to the development of artificial refrigeration techniques during the 1800s, people utilized a variety of means to chill and preserve foodstuffs. For centuries, ice served as the principal refrigerant. Ironically, the ancient Indians and... Read more
Freons Freons
Freons The trademark Freon refers to any of several gaseous chlorofluorocarbons, CFCs, with the general formula CF xCl 4-xor C 2F xCl 6-x. Due to their physical and chemical properties, these CFCs became the compounds of choice as propellants... Read more
Hydrochlorofluorocarbons Hydrochlorofluorocarbons
Hydrochlorofluorocarbons Why HCFCs? Benefits and costs of HCFCs The future of HCFCs Resources Hydrochlorofluorocarbons (HCFCs) are compounds consisting of hydrogen, chlorine, fluorine, and carbon atoms. HCFCs and hydrofluorocarbons (HFCs) were created in the 1980s as substitutes for... Read more
air conditioning air conditioning
air conditioning mechanical process for controlling the humidity, temperature, cleanliness, and circulation of air in buildings and rooms. Indoor air is conditioned and regulated to maintain the temperature-humidity ratio that is most comfortable and healthful. In the process, dust, soot, and... Read more
hygrometer hygrometer
hygrometer , instrument used to measure the moisture content of a gas, as in determining the relative humidity of air. The temperature at which dew or frost forms is a measure of the absolute humidity—the weight of water vapor per unit volume of air or other gas at the temperature before... Read more
