What does argon look like?
A noble gas, argon is inert and colorless until an electric current excites it to a rich sky-blue glow. As one of the least expensive noble gases, dense argon is often used as a shield gas to protect against oxidation.
Does argon turn to liquid?
Argon gas condenses to a colourless liquid at −185.8 °C (−302.4 °F) and to a crystalline solid at −189.4 °C (−308.9 °F). The gas cannot be liquefied by pressure above a temperature of −122.3 °C (−188.1 °F), and at this point a pressure of at least 48 atmospheres is required to make it liquefy.

Is argon odorless and colorless?
Argon is a colorless, odorless, unreactive gas which liquefies at -185.8°C (87.3 K).
How much does argon cost?
Argon gas cylinders are considered the most expensive, with prices going up to $350 for a new cylinder.
How cold is liquid argon?
Cryogenic liquids are liquefied gases that have a normal boiling point below –130°F (–90°C). Liquid argon has a boiling point of –303°F (–186°C). The temperature difference between the product and the surrounding environment, even in winter, is substantial.
Is argon a toxic gas?
A: Argon is an inert, non-toxic gas. It’s denser than oxygen and present in 1 percent of the air we breathe. It’s an extremely stable element with non-reactive properties.
Is Argon bad to breathe?
Inhalation: This gas is inert and is classified as a simple asphyxiant. Inhalation in excessive concentrations can result in dizziness, nausea, vomiting, loss of consciousness, and death. Death may result from errors in judgment, confusion, or loss of consciousness which prevent self-rescue.
What color does argon burn?
Argon has no color or smell. It does not burn. It’s heavier than air and will tend to settle in low-lying areas. Argon is slightly water soluble. Argon is a member of a special group of gases known as the “noble” or “inert” gases. Other gases in this group are helium, neon and kryp- ton.
How common is argon?
Argon is a gaseous chemical element that makes up almost 1% of the Earth’s atmosphere. Among the noble gases, it is generally considered to be the most abundant, and it is sometimes used to replace other noble gases in situations where an inert gas in needed.
What does argon do?
Argon, a noble gas, is used to create a shield for arc wielding, as well as in lighting and fire extinguishers.
