Mis-labelling in phase diagram? edit

Aren’t the axes the wrong way round in the p-T diagram? If the critical point is going to be in the lower branch of the Y, shouldn't T be the x-axis? Compare Supercritical fluid#Phase diagram. And the gas/liquid/solid labels make no sense for either choice of axes. Or am I missing something? SteepLearningCurve (talk) 16:54, 21 July 2015 (UTC)Reply

I Agree: the diagram is wrong. The diagram suggests that the substance is a liquid at high pressure and low temperature whereas it is shown as a solid at high temperature and low pressure. So far I haven’t encountered any substance with such properties. Relabelling the axis doesn't fix it. Especially since it really should’t matter if you choose the x or y- axis for the temperature. But I’d prefer the more common pT-Diagram instead of the given Tp-Diagram. The Diagramm as show is completely misleading. Cgn21 (talk) 17:35, 6 August 2015 (UTC)Reply

The gas and liquid labels are reversed. I've removed it for now. If it is fixed, it can be restored. Moreover, it would be better not to have a scan of a handdrawing. --JorisvS (talk) 09:34, 7 August 2015 (UTC)Reply
