Using the phase diagram for CO_2, what phase is carbon ... - Socratic
Jul 31, 2017 · The gas phase A phase diagram for "CO"_2: What we do is take the vertical line of -20 ""^"o""C" and the horizontal line of 1 "atm" (not explicitly shown here, but it is essentially the bottom of the graph) and find in what phase region they intersect. Carbon dioxide appears to be in the gaseous state at -20 ""^"o""C" at all pressures below 20 "atm", so it will be in the gas phase.
Using the phase diagram for CO_2, what phase is carbon ... - Socratic
Jul 20, 2017 · Well, consult the phase diagram. And then you literally just read it like any other graph: find your x coordinate and find your y coordinate. (x,y) -= (P,T) = ("15 atm", -60^@ "C") And one should easily see that "CO"_2 is a solid at this T and P, as it should be, left of its triple point temperature but higher up than the triple point pressure. We call this dry ice; once …
What are the phase diagrams of water and carbon dioxide?
Nov 23, 2017 · Each line represents phase changes between respective boundaries. The triple point is where all the phases are at equilibrium. Phase changes are usually isothermal, so temperature is constant until every molecule has attained high enough heat (e.g. kinetic energy) to surpass the intermolecular forces characteristic of each phase at varying strengths.

(ii) Compare this phase diagram with that exhibited by water. (a) Look at the CO2 phase diagram and explain the common sight of solid CO2 blocks subliming when under normal atmospheric pressure (1.0 bar = 1 atmosphere) conditions rather than evaporating from a liquid (as water does at normal atmospheric pressure).
