Solution: Based on the phase diagram of CO2 shown in the figure, describe the phase changes that occur when the temperature of CO2 is increased from 190 K to 350 K at a constant pressure of 1 atm.

Problem

Based on the phase diagram of CO2 shown in the figure, describe the phase changes that occur when the temperature of CO2 is increased from 190 K to 350 K at a constant pressure of 1 atm. The diagram depicts temperature, in degrees celsius, versus pressure, in atmospheres. The first line segment begins at the origin, and curves upward to the triple point, at (-56.7,5.1). From there a line with a large positive slope extends upward to the top of the graph. The area to the left of this line, and above the first is labled solid. From the triple point another line extends from it, curving upward to the critical point at (31,72.9). The area above this line, and to the right of the upward line, is labled liquid. The area below both curved lines is labled gas.
