Can an inert gas be frozen into a solid?
In short: Watch as technician Andrew Marmery demonstrates the extreme conditions required to transform Argon from a gas into ice. This experiment reveals the delicate thermal boundaries that define the behavior of noble gases.
In the Royal Institution's prep room, Andrew Marmery explores the phase changes of Argon. While typically an inert gas at room temperature, Argon can be frozen into a solid if temperatures drop below -189.3 degrees Celsius. The liquid phase of Argon is notably unstable, existing within an extremely narrow temperature range of only three to four degrees Celsius before it transitions almost instantaneously into a gas as it warms.
