Physical Properties of Ammonia
| Property | Description |
|---|---|
| Physical State | Colourless gas |
| Odour | Distinct pungent odour, known as ammoniacal odour |
| Density Relative to Air | Lighter than air, gathered via air displacement downward |
| Effect on Inhalation | Causes tears to well up in the eyes when inhaled quickly |
| Liquefaction Conditions | Easily liquefies at room temperature under a pressure of 8 to 10 atmospheres |
| Boiling Point under 1 atm | –33.5°C (239.6K) |
| Enthalpy of Vaporization | High (1370J/g), used in ice-making equipment and refrigeration systems |
| Freezing Point | Freezes into a white crystalline solid at –77.8°C (195.3K) |
| Water Solubility | Extremely high; one volume of water dissolves about 1300 volumes of ammonia gas |
| Collection Method | Cannot be collected in water due to its high water solubility |
