Hi, I am wondering where to find data on carbon dioxide at 298k. Temperature volume latent heat etc.

Sorry to crash your thread PenKnight, but I have a question too.  I always thought that CO2 sublimed from solid to Gas and that there was no liquid stage.   Obviously the liquid phase will be possible at certain temperature pressure scenarios on its phase diagram, but at a standard 1 atmosphere, do we get liquid CO2?   What causes the confusion if not as lots of people talk about liquid CO2 as if it were common, but as I said - I've always known it to sublime?

I don't think carbon dioxide can exist as liquid at 1 atm. The pressure must be at least greater than 5.1 atm for liquid to be formed.

Thanks for the link but that diagram is way to small. But the page did give a nice google term and I found it

Very nice. How valid are this graphs?
