The phase diagram of carbon is a graph of pressure (y-axis or dependent variable) versus temperature...
Please refer to the phase diagram on slide 38 in the lecture notes for Carbon and answer the following questions. a) b) c) d) How many triple points are in the phase diagram? What phases can coexist at each triple point? What happens if graphite is subjected to very high pressure at room temperature? If we assume that the density increased with an increase in pressure, which is more dense,graphite or diamond?
5) Consider the phase diagram for carbon dioxide(10). Supercritical fluid Solid Liquid Pressure (atm) -78.5 -56.4 Temperature (°C)— a) What is the critical temperature for carbon dioxide? b) What is the critical pressure for carbon dioxide? c) What phase(s) is/are present at -10°C and 30 atm. d) What phase(s) is/are present at -60°C and 10 atm. - e) What phase(s) is/are present at-78.5°C and 1 atm. f) What phase(s) is/are present at-56.4°C and 5.11 atm. g) What is the normal...
