At standard temperature and pressure, ammonia is less dense than atmosphere and has approximately 45-48% of the lifting power of hydrogen or helium. Ammonia has sometimes been used to fill weather balloons as a lifting gas. Because of its relatively high boiling point (compared to helium and hydrogen), ammonia could potentially be refrigerated and liquefied aboard an airship to reduce lift and add ballast (and returned to a gas to add lift and reduce ballast). Show The other three gases are all heavier than air and therefore would not be used for weather balloons. Ammonia is a compound of nitrogen and hydrogen with the formula NH3. The simplest pnictogen hydride, ammonia, is a colourless gas with a characteristic pungent smell. It is a common nitrogenous waste, particularly among aquatic organisms, and it contributes significantly to the nutritional needs of terrestrial organisms by serving as a precursor to food and fertilizers. Although common in nature and in wide use, ammonia is both caustic and hazardous in its concentrated form. It is classified as an extremely hazardous substance in the United States, and is subject to strict reporting requirements by facilities which produce, store, or use it in significant quantities.

The main reasons for these gases lie in their properties like their reactivity and their density and weight. Complete step by step answer: Note:

It is an inert gas as it does not react with other substances.. It is non-flammable.. It is a lightweight gas and possesses low density.. Why hydrogen gas is used for fill weather balloons?A balloon filled with hydrogen is used in meteorological balloons to study weather conditions because it is less dense than air. This makes it float and helps lift the balloon up in the air.
Do weather balloons use hydrogen?Typically, we will fill the balloon with about 1400 grams of hydrogen. Here, the balloon is shown completely inflated. Attached to the balloon is the "train", which consists of a parachute and the instrument package (called a radiosonde).
