So I'm confused (like perpetually). Some have said the CO2 in the cartridges is in liquid state. For some reason, I have a vague recollection from a chemistry class somewhere saying that CO2 was never liquid, it just sublimated directly from solid to gas. Though I suppose pressure might put it in an unnatural state. Any chemistry whizzes want to enlighten me?
