Phase Diagram Of Carbon Dioxide

Carbon dioxide is 57ºc at 52 atm and water is 001ºc at 0006 atm figure 1. Sublimation curve vaporization curve triple point critical temperature and pressureof course the p and t values of are unique to carbon dioxide.

Phase diagram of carbon dioxide. Carbon dioxide is a gas at standard conditions. The unique triple point for co2 and h2o also explains the differences in the phase diagrams. Phase diagrams for a pure compound such as phase diagrams for water and carbon dioxide are phase diagrams for a single component system.

At temperature of 1975 k 785 o c the vapor pressure of solid carbon dioxide is 1 atm 760 torr. In the following phase diagrams shown that the triple point of carbon dioxide occure at a pressure of 52 atm 3952 torr and 2166 k 564 o c. The phase diagram for carbon dioxide shows the phase behavior with changes in temperature and pressure.

At this pressure the liquid phase is not stable the solid simply sublimates. The phase diagram of co2 is similar to the phase diagram of water. In these diagrams pressure p and temperature t are usually the coordinates.

Natural sources include volcanoes hot springs and geysers and it is freed from carbonate rocks by dissolution in water and acids. The triple point is 566c and 511 atm which means that liquid co 2 cannot exist at pressures lower than 511 atm. However at low temperature andor high pressures the gas becomes a liquid or a solid.

The current concentration is about 004 410 ppm by volume having risen from pre industrial levels of 280 ppm. That means that at 1 atmosphere pressure carbon dioxide will sublime at a temperature of 78c. This is the reason that solid carbon dioxide is often known as dry ice.

Liquid co2 can be produced only at pressures above 5atm. Solid co2 is more dense than liquid co2. You cant get liquid carbon dioxide under normal conditions only the solid or the vapour.

It occurs naturally in earths atmosphere as a trace gas. Solid co2 sublimes when heated. The phase diagram for carbon dioxide.
