Anhydrous Ammonia

Ammonia, in its anhydrous liquid form, is a pure chemical substance rather than just an industrial gas. It is characterized by fixed melting and boiling points, specifically -77.7°C and -33.4°C, respectively. When forming chemical compounds, heat is either released or absorbed. In the case of ammonia, the properties of the compound are markedly different from those of its constituent elements, hydrogen and nitrogen. Although these elements combine in a specific volumetric ratio of 3:1 (hydrogen to nitrogen), the resultant compound, ammonia, exhibits distinct characteristics that set it apart from its individual elements.
