2025年3月12日 · Ammonia is a colourless gas with a sharp, penetrating odour. Its boiling point is −33.35 °C (−28.03 °F), and its freezing point is −77.7 °C (−107.8 °F). It has a high heat of vaporization (23.3 kilojoules per mole at its boiling point) and can be handled as a liquid in thermally insulated containers in the laboratory.

Ammonia occurs naturally and is produced by human activity. It is an important source of nitrogen which is needed by plants and animals. Bacteria found in the intestines can produce ammonia. Ammonia is a colorless gas with a very distinct odor.

2023年4月28日 · Ammonia is a naturally occurring gas that serves as a chemical building block for a range of commercial and household products, including fertilizers and cleaning supplies. Additional uses include as a refrigerant, stabilizer, neutralizer, and purifier — particularly in food transport and water treatment applications.

2022年7月23日 · Ammonia, NH3, is a colorless gas with a pungent, irritating odor that is produced by combining large amounts of nitrogen and hydrogen. The Haber-Bosch process is the most common commercial method of producing ammonia.

ammonia, Colourless, pungent gas composed of nitrogen and hydrogen, chemical formula NH 3. Easily liquefied by compression or cooling for use in refrigerating and air-conditioning equipment, it is manufactured in huge quantities.

2021年2月8日 · Ammonia is a colorless, poisonous gas with a familiar noxious odor. It occurs in nature, primarily produced by anaerobic decay of plant and animal matter; and it also has been detected in outer space. Some plants, mainly legumes, in combination with rhizobia bacteria, “fix” atmospheric nitrogen to produce ammonia.
