Which property allows ammonia to form a clear liquid when compressed?

• A. It is colorless and highly irritating
• B. It has a sharp suffocating odor
• C. It dissolves easily in water
• D. It is denser than air

Answer: (C)

The ability of ammonia to form a clear liquid when compressed is primarily attributed to its physical properties, particularly its ability to dissolve easily in water. Ammonia, when subjected to high pressure and low temperature, transitions from a gaseous state to a liquid state. This occurs because the kinetic energy of the molecules decreases, allowing them to come closer together and form a liquid. While ammonia is colorless and has a sharp odor, these characteristics do not directly influence its ability to liquefy under compression. Additionally, while ammonia is denser than air, this property also does not facilitate the formation of a clear liquid upon compression. In contrast, its solubility in water emphasizes its interaction at a molecular level, which is fundamentally tied to its physical transformation from gas to liquid when pressure is applied.
