Schematic P–T phase diagram of CO₂: dry ice, liquid, gas, positive solid–liquid slope, triple point −56.6 °C / 5.11 atm, critical point 31.0 °C / 72.8 atm, sublimation at −78.5 °C. ## What the template shows - The triple point lies above 1 atm, so solid CO₂ sublimes instead of melting - sublimes at 1 atm - Solid (dry ice) - Triple point - Critical point - schematic, not to scale - Triple point at −56.6 °C and 5.11 atm: liquid CO₂ only exists above 5.11 atm, so at 1 atm dry ice sublimes at −78.5 °C. - The solid–liquid line slopes to the right (positive), as for most substances: the solid is denser than the liquid. - Critical point 31.0 °C, 72.8 atm: supercritical CO₂ is a mild, easily removed solvent (decaffeinating coffee, extraction). - CO₂ fire extinguishers hold the liquid under its own vapour pressure, about 57 bar at 20 °C. - Every part of this figure is editable · sources on the template card Drawn with 171 shapes – every one editable in MolDraw. ## Sources - [Atkins, de Paula & Keeler, Atkins' Physical Chemistry, 11th ed., OUP 2018, ch. 4](https://openlibrary.org/isbn/9780198769866) Textbook - [NIST Chemistry WebBook: carbon dioxide](https://webbook.nist.gov/cgi/cbook.cgi?ID=C124389) Database ## How to use this template 1.

You can preview the Phase diagram of carbon dioxide template here and open and edit it in MolDraw for free. Downloading or exporting it is part of MolDraw Pro, together with the other premium templates. ### Can I edit the Phase diagram of carbon dioxide template? Yes. It opens as an ordinary MolDraw drawing, so every structure, arrow, label and colour can be changed, and you can add your own content around it. ### Is the chemistry checked? Every structure is checked with RDKit and every curly arrow passes MolDraw’s electron-flow audit. The sources used are listed on this page. ### Which MO diagrams are included? H₂ and He₂, N₂ and O₂ (showing s–p mixing and paramagnetic O₂), and carbon monoxide. ## More general & inorganic templates [**VSEPR shapes**Free · General & inorganic](https://www.moldraw.com/templates/genchem-vsepr-shapes/)[**MO diagrams: N₂ and O₂**Free · General & inorganic](https://www.moldraw.com/templates/genchem-mo-n2-o2/)[**Crystal field splitting**Free · General & inorganic](https://www.moldraw.com/templates/genchem-crystal-field/)[**Born–Haber cycle: NaCl**Premium · General & inorganic](https://www.moldraw.com/templates/genchem-born-haber-nacl/)[**MO diagram: H₂ and He₂**Premium · General & inorganic](https://www.moldraw.com/templates/genchem-mo-h2/)[**MO diagram: carbon monoxide**Premium · General & inorganic](https://www.moldraw.com/templates/genchem-mo-co/)[**High spin and low spin: d⁶**Premium · General & inorganic](https://www.moldraw.com/templates/genchem-high-low-spin/)[**Hess's law: ΔfH of carbon monoxide**Premium · General & inorganic](https://www.moldraw.com/templates/genchem-hess-co/) ## Related pages [**VSEPR & Molecular Geometry Worksheet**Free printable worksheet](https://www.moldraw.com/educational-materials/vsepr-molecular-geometry-worksheet/)[**Lewis Structure Worksheet**Free printable worksheet](https://www.moldraw.com/educational-materials/lewis-structure-worksheet/)[**Printable Periodic Table**Free printable worksheet](https://www.moldraw.com/educational-materials/printable-periodic-table/)[**All General & inorganic templates**12 templates](https://www.moldraw.com/templates/general-and-inorganic/)[**All chemistry templates**370 templates in 29 categories](https://www.moldraw.com/templates/) MolDraw Pro Download all 370 templates - Export the 291 premium templates as PNG, SVG or PDF - AI chemistry assistant - Structure scanning from images - Cloud save and teaching slides [See Pro plans](https://www.moldraw.com/pricing) Free templates stay free.
