Why is ammonia in gas form at room temperature?

Answer 1

Actually ammonia or NH3 is a colourless gas with pungent smell at room temperature. But at room temperature liquid ammonia can also be prepared artificially. To prepare liquid ammonia, 88 g NaOH and 107 g NH4Cl is reacted. Then the produced NH3 gas is held on dry ice acetone bath or some ammount of water is added dropwise in that furnace where the reaction of NaOH and NH4Cl occurred. Then we will get liquid ammonia. The associated reactions are -

NaOH + NH4Cl → NaCl + NH3 (g) + H2O

2. NH3(g) + (Water drop or dry ice bath) → liquid ammonia

So at room temterature Liquid ammonia can be prepared and it is stable enough and can react with metals like Na or Li, but Solid ammonia does not exist. But it can exist as ammonium salt.

Answer 5

That is because ammonia's boiling point is -33.34 Celsius or -28 Fahrenheit. The average household temperature is about 28 to 32 Celsius depending where you live but wherever it is, it is definitely above the boiling point of ammonia.

Answer 8

Largely the same way nitrogen, oxygen, hydrogen, helium, argon, carbon monoxide, carbon dioxide, methane, ethane, water, and a host of other, similar, lightweight molecules are gases at room temperature and pressure. All of these can be forced into a liquid phase by either lowering the temperature, increasing the pressure or both.

The deciding factor is really density. Ammonia, specifically, is NH3, composed of nitrogen and hydrogen. Water vapor is H2O, composed of oxygen and hydrogen. Carbon dioxide is CO2, composed of carbon and oxygen. As long as the density of the resultant molecule is low enough, it will retain the nature of the majority of its constituent atoms, that of being a gas at standard temperature and pressure.

Once the molecules get large enough, or the single central atom is large enough, then it doesn’t matter how many atoms, which are gasses at S.T.P., are chemicly bonded to it, it will be unable to be a gas at S.T.P. One chemical name for ammonia is hydrogen nitride. Titanium nitride (TiN) is a popular surface treatment for metal machine parts and is not a gas. This is because the Titanium atom is so much denser, having both more bosons in fewer nuclei, than the three hydrogen atoms it replaces, making it a solid at S.T.P.

Answer 9

ammonia does not form hydrogen bonding.So there is no grouping of molecules. hence ammonia is gas at room temperature.

Answer 10

Ammonia unlike Water has very little hydrogen bonding. Because the nitrogen is less electronegative than oxygen of water.
