In order to illustrate the nature of the critical point, one can place CO₂ in a quartz vial and seal the device. Assuming that v_c = 0.002 m³/kg, and that the device is filled at room temperature (290 K), use the T–s chart in Appendix A.9 to find:

a. The pressure in the vial at room temperature,
b. The percent liquid mass and volume ensuring passage through the critical point upon heating Calculate v^L from x, v_LV, and v^V).
