Argon Ice

In the video above, argon is liquified and frozen (wut), using liquid nitrogen, ultimately producing argon ice (double wut). I think it’s quite interesting to think of a solid noble gas.

At room temperature, argon exists as a gas. Argon has a melting point of -186.36 °C (-303.448 °F) and a boiling point of -185.847 °C (-302.525 °F) . The narrow range between the melting and boiling points is demonstrated around 4:37 when the drops of liquid argon immediately boil as it lands on the surface.

Fun fact: argon is the third most abundant gas (0.93%) in the earth’s atmosphere, behind nitrogen (78.09%) and oxygen (20.95%).
