Consider the following data for a substance: Critical point: 115.1 atm and 570°C Triple point: 0.107 atm and 117°C Normal melting point: 1.00 atm and 125°C What is the normal boiling point of the substance? Enter your answer in units of °C to three significant figures.
Among other things, phase diagrams help us predict those conditions under which a substance will exist as a supercritical fluid. Supercritical CO2 is especially useful as it is very effective at dissolving nonpolar oils which constitute many of the flavouring or odor-causing compounds in foods. For example, food companies use supercritical CO2 to extract caffeine from coffee. a) Use the following data to label the following points on the phase diagram for CO2: Triple point -57°C, 5.1 atm, Normal sublimation...
Sketch a phase diagram for a substance given the following information: the triple point occurs at 54.3 K and 0.00015 MPa; the critical point occurs at 154.6 K and 5043 MPa; the normal melting point is 54.8 K; and the normal boiling point is 90.25 K. Does this solid melt under applied pressure? Why?
