What temperature does the argon liquid start at?
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.
What state is argon in at room temperature?
noble gas
Argon is a chemical element with symbol Ar and atomic number 18. Classified as a noble gas, Argon is a gas at room temperature.
How does the phase of argon change with temperature?
However, at low temperature and/or high pressures the gas becomes a liquid or a solid. The argon phase diagram shows the phase behavior with changes in temperature and pressure. The curve between the critical point and the triple point shows the argon boiling point with changes in pressure.
When does an argon gas become a liquid?
Argon is a gas at standard conditions. However, at low temperature and/or high pressures the gas becomes a liquid or a solid. The argon phase diagram shows the phase behavior with changes in temperature and pressure.
How to calculate argon density at temperature and pressure?
Tabulated values of argon density at given temperature and pressure (SI and Imperial units) as well as density units conversion are given below the figures. The calculator below can be used to estimate the density and specific weight of argon at given temperature and pressure.
What happens to argon gas in the workshop?
Wind will blow your Argon gas away from your weld puddle and lead to porosity. But even a mild through draft in your workshop will see you upping your Argon gas CF rate. And then you’ll be using more Argon out of your 20 cf tank.
