1a. Consider a compound with two solid phases, a low-pressure phase and a high-pressure phase(like carbon). Sketch the phase diagram for this compound, assuming that both solid phases are denser than its liquid phase. Identify all the important components of the diagram.

1b.For each option below, choose the one with a higher vapor pressure. Explain your answer please.

a)Methane vs Methanol. c) water at 20 degs C vs water at 80 degs C

b) ocatane vs hexane d) 10 mL of benzene vs 100 mLof benzene
