Phase Diagram for \(\mathrm{CO} 2\) The phase diagram for \(\mathrm{CO}_{2\) is shown in Figure 17–29.
(a) What is the phase of \(\mathrm{CO}_{2} \text { at } \mathrm{T}=20^{\circ} \mathrm{C} \text { and } \mathrm{P}=500 \mathrm{kPa}\)?
(b) What is the phase of \(\mathrm{CO}_{2} \text { at } \mathrm{T}=-80^{\circ} \mathrm{C} \text { and } \mathrm{P}=120 \mathrm{kPa}\)?
(c) For reasons of economy and convenience,bulk \(\mathrm{CO}_{2\) is often transported in liquid form in pressurized tanks. Using the phase diagram, determine the minimum pressure required to keep \(\mathrm{CO}_{2\) in the liquid phase at \(20^{\circ} \mathrm{C}\)
