What is the main use of argon?

Argon is often used when an inert atmosphere is needed. It is used in this way for the production of titanium and other reactive elements. It is also used by welders to protect the weld area and in incandescent light bulbs to stop oxygen from corroding the filament.

What is Argon most commonly used for?

Argon is obtained from the air as a byproduct of the production of oxygen and nitrogen. Argon is frequently used when an inert atmosphere is needed. It is used to fill incandescent and fluorescent light bulbs to prevent oxygen from corroding the hot filament.

Which is the most Liquefiable gas?


Which gas will liquefy most easily?

NH3 can be liquefied easily as its molecules can interact through intermolecular hydrogen bonding which is possible because an H atom is directly bonded to a highly electronegative N atom with a lone pair.

Is used for liquifying of gas?

Pioneer work on the liquification of gases was carried out by the English scientist Michael Faraday (1791-1867) in the early 1820s. Faraday was able to liquify gases with high critical temperatures such as chlorine, hydrogen sulphide, hydrogen bromide, and carbon dioxide by the application of pressure alone.

How can we liquify gas?

In general, gases can be liquefied by one of three methods: (1) by compressing the gas at temperatures less than its critical temperature; (2) by making the gas do some kind of work against an external force, which causes the gas to lose energy and change to the liquid state; and (3) by making gas do work against its …

Why is gas liquefied?

Natural gas is liquefied by lowering the temperature of the hydrocarbon to approximately -260 degrees Fahrenheit (-160 degrees Celsius). This temperature drop liquefies the methane present in the natural gas, making transportation at atmospheric pressure in the form of LNG possible.

How can we liquefy a gas Class 9?

Answer: In order to liquefy a gas, the constituent particles or molecules have to be brought closer. The atmospheric gases can be liquefied either by increasing pressure or by decreasing temperature.

How do you liquify ammonia gas?

At temperatures below –33°C ammonia turns liquid at atmospheric pressure. Increasing the pressure by itself suffices to liquefy the gas: at 20°C a pressure of 7.5 bar is adequate. In its pressure-liquefied state anhydrous ammonia requires special conditions for storage and handling.

How does applying pressure help in liquefaction of gas?

Pressure brings close to molecules of a gas that are far apart from each other. When more and more pressure is applied on gas molecules they come closer to each other so inter molecular forces start producing between gas molecules. This factor helps in liquefaction of gases.

At what temperature does ammonia become liquid?

Ammonia is a colourless gas with a characteristically pungent smell. It is lighter than air, its density being 0.589 times that of air. It is easily liquefied due to the strong hydrogen bonding between molecules; the liquid boils at −33.3 °C (−27.94 °F), and freezes to white crystals at −77.7 °C (−107.86 °F).
