Question

which of the following cannot be determined by looking at the phase diagram? A. melting point, B. boiling point, C. subilmation point D. system pressure.

Answer 1

 I am pretty sure that the following whihc cannot be determined by looking at the phase diagram is definitely D. system pressure.  I consider this one to be correct because only this point is not included into phase diagram and can't be determined itself. Hope it will help! Regards!
