Venus And CO2

Carbon dioxide makes up about 96 percent of the atmosphere of Venus, but some researchers say at one time the planet may have had oceans of carbon dioxide fluid.

That would've been supercritical CO2.  In a supercritical state, carbon dioxide can shift between being a gas and being a liquid and back virtually instantaneously.  Venus would have been a really strange place.
