Fluid Mechanics - The study of fluids - liquids and gases.The triple point of a substance is the temperature and pressure at which the three phases (gas, liquid, and solid) of that substance coexist in thermodynamic equilibrium.īack to top Atmospheric CO 2 Concentration Carbon dioxide in solid phase is called dry ice.Īt the critical point there is no change of state when pressure is increased or if heat is added. The curve between the triple point downwards to zero pressure shows the sublimation point with changes in pressure (Sublimation: transformation from solid phase directly to gas phase). The curve between the critical point and the triple point shows the carbon dioxide boiling point with changes in pressure. The phase diagram for carbon dioxide shows the phase behavior with changes in temperature and pressure. However, at low temperature and/or high pressures the gas becomes a liquid or a solid.

It is relatively nontoxic and noncombustible, but it is heavier than air and may asphyxiate by the displacement of air. ![]() Carbon dioxide, CO 2, is a colourless and odorless gas.
