Immediately Evaporating Argon Ice

Andrew Marmery from The Royal Institution in London experiments with argon ice in the video below, including some intriguing comments on argon’s atomic weight, and which shows how quickly argon shifts from solid to gas (it melts at −189.35 °C, and evaporates at −185.85 °C, so in less than 4 degrees Celsius it shifts through all three phases!).

With the nor’easter Nemo having passed through town overnight, I’m reminded to be happy that snow isn’t constituted from solid argon, otherwise that would mean it’s really cold outside.
