The melting point and boiling point of argon are 83.81 K and 87.302 K respectively. So argon is liquid in between these two temperatures.
Liquid argon could in theory be used for cryogenics, but it has a similar temperature range to liquid nitrogen, which is tremendously cheaper and more abundant than argon. For the lower temperature ranges, you would use liquid helium.
Argon cannot freeze. The temperatures required would be below absolute zero which is impossible to achieve. Therefore the answer is unknown.
Solid Argon is more dense than the liquid phase
I think its a gasIt is a gas at room temperature, however, at lower temperature or higher pressure it can be a liquid or even a solid. Think about H2O is it a liquid? It depends on temperature and pressure. water, ice and steam are all H2O, but at different tempertures.
that depends on the temperature and pressure, at room temperature and pressure argon is a gas
No. Argon is a gas at room temperature.
Liquid argon could in theory be used for cryogenics, but it has a similar temperature range to liquid nitrogen, which is tremendously cheaper and more abundant than argon. For the lower temperature ranges, you would use liquid helium.
Argon is a gas at room temperatures.
It can be a solid liquid or a gas, depending on the temperature
At room temperature and normal atmospheric pressure it is a gas.
Argon can be transformed in to a liquid. Argon changes from a gas to a liquid at -185.86°C (-302.55°F).
Argon cannot freeze. The temperatures required would be below absolute zero which is impossible to achieve. Therefore the answer is unknown.
This depends on temperature and pressure, consider h2o. Is "water" a solid liquid or gas? Clouds are water vapor as is steam, rivers oceans and lakes are liquid, and icebergs are solids. However, Argon is a gas in earths atmosphere so at those conditions it is a gas. Argon is solid at temperatures below -189.3°C, at which temperature it liquefies. It is a gas at temperatures of -185.86°C and higher.
Solid Argon is more dense than the liquid phase
Depends entirely upon pressure. At one atmosphere, Ar liquifies at -186C
By heating uranium at a temperature above the melting point (1132,2 0C), in an argon atmosphere.
Compression. Argon is turn to liquid by compression and removing heat. Typically this is done through refrigeration using liquid nitrogen. Most liquid argon is produced in a plant that makes liquid O2,N2 and Ar. It is the rarest of the 3.
