Hi.

Can anybody help me with crystals?
I have a gas that makes blue crystals when it's been hold in low temperature and high pressure. If pressure becomes higher, it makes red crystals, if pressure becomes lower then it reurns to the blue color. If pressure stil becomes lower and temperature higer, then it makes blue liquid.
Can anybody help me with this? I would be extremely grateful :)
Thank you in advance and have a nice day! :))

thanks, I found the answer :)
