How do you find the boiling point of argon?
Argon – Melting Point and Boiling Point Melting point of Argon is -189.2°C. Boiling point of Argon is -185.7°C. Note that these points are associated with the standard atmospheric pressure.
At what pressure does argon become liquid?
48 atmospheres
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.

How is argon gas consumption calculated?
argon flow is measured in cu f/h or litres/minute, value should be around 15-20 cf/h or 7-10 l/min (I’m thinking TIG or GTAW here). time x argon flow = total volume of Ar consumed.
What is the melting point for argon?
What is the triple point of argon?
The triple point of pure Argon has been measured and the value obtained is t* = -189.3331 °C where t* refers to a temperature scale obtained by extrapolating the Callendarvan Dusen equation.
What is Argon formula?
The formula for Argon Gas is Ar. It has the atomic number 18 and is a noble gas. Argon Gas has the molecular formula Ar. Argon is a non-combustible gas that is colourless and odourless.
Why argon is a gas at room temperature and pressure?
Several of the nonmetals are gases in their elemental form. The noble gases of Group 8A (He, Ne, Ar, Kr, Xe, and Rn) are all gases at room temperature (as the name of the group implies); since they are all unreactive, monatomic elements, their boiling points are extremely low.
What is the melting point of K?
146.3°F (63.5°C)
Potassium/Melting point
What is the boiling point of argon at room temperature?
Boiling point of Argon is -185.7°C. Note that, the boiling point associated with the standard atmospheric pressure. In general, boiling is a phase change of a substance from the liquid to the gas phase.
Is argon a solid liquid or gas at high pressure?
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 do you find the boiling point at different pressure values?
If the boiling point values for a specified substance at a specified BP temperature and pressure are given, one can determine the Boiling Point at different vapor pressure values using the Clausis-Clapeyron Equation. The Clausis-Clapeyron Equation is derived from #VP_2 = VP_1e^(-DeltaH_v/(RT))# at two different temperatures.
What does the argon phase diagram show?
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. It also shows the saturation pressure with changes in temperature.
