CHE-126 General Chemistry II Exercise 2. Phase Diagrams 2. Using the phase diagram for carbon (below) as your only source of information 3. Dad Polen Vupor 4000 GO Tenger, K a) What phase(s) of carbon would you expect to observe at a temperature of 4000 K and a pressure of 100 kg/cm? Vapor b) Which is denser, graphite or liquid carbon2 Graphite c) What phase(s) of carbon are stable at 2000 K and 1000 kg/cm2 Graphite d) What would happen to a piece of graphite if you subjected it to a temperature of 100 K and a pressure of 105 kg/cme? Could you coat an object with graphite by depositing it from the vapor phase? If so, what conditions must you use
