I stumbled upon a really cool video today showcasing the phenomenon of triple point, which is when the temperature and pressure are just right for an element so that it exists in all three phases, gas, liquid, and solid.
For water that is at 0.01° C and at a pressure of 0.006 atm.
Imo, it's really mind blowing to see water boiling, melting and forming ice..all at the same time!
Enjoy:
And here's a video explaining the triple point in more detail
Cool shit!
