Tales from the Prep Room: Argon Ice (2011x5)
:
The Ri's very own demo technician, Andrew Marmery experiments with the element Argon in the Ri Prep Room.
At room temperature Argon is an inert gas, requiring temperatures of below -189.3 degrees Celsius to freeze into a solid. The temperature range at which Argon exists as a liquid is extremely narrow (three/ four degress). As it begins to melt under room temperature it passes into its gas state almost instaneously.
