[PDF] phase diagram of water and carbon dioxide

How do you interpret the phase diagram of water and carbon dioxide?

Interpret the phase diagram of water and carbon dioxide. pressure versus temperature. Phase diagrams contain discrete regions corresponding to the solid, liquid, and gas phases. states is negative rather than positive. The reason is that water is an unusual substance in that its solid state is less dense than the liquid state.

What is a phase diagram?

A phase diagram shows the temperatures and pressures at which the various phases (i.e., solid, liquid and vapor) of a substance can exist. Both phase diagrams for water and carbon dioxide have the same general

What is the phase of carbon dioxide at 25 degrees Celsius?

Now we can look at the diagram and determine its phase. At 25 degrees Celsius and 1 atm carbon dioxide is in the gas phase. 2: Carbon dioxide sublimes at 1 atm because it transitions from the solid phase directly to the gas phase. The temperature of sublimation at 1 atm is about -80 degrees Celsius.

What is the triple point of the CO2 phase diagram?

C is the triple point of the CO2 phase diagram. This means that at the temperature and pressure corresponding to this point (i.e., at –56.6°C and 5.11 atm), the solid, liquid, and vaporous phases of CO2 co-exist in equilibrium. (b) The fusion and boiling points of CO2 decrease with a decrease in pressure.
