1) What is the critical temperature of compound x? 770 2) If you were to have a bottle containing compound x in your closet, what phase would it most likely be in? (room temp is 21 degrees C) solid 3) At what temperature and pressure will all three phases coexist? 350 C and 50 atm 4) If I have a bottle of compound X at a pressure of 45 atm and temperature of 100 degrees C what will happen if I raise the temperature to 400 degrees C? turns into a gas 5) Why can't compound X be BOILED at temperature of 200 degrees C? because that's not the boing point and its still a solid 6) what state of matter is compound x at 400 degrees and 30 atm? gas 7) what state of matter is compound x at 400 degrees and 60 atm? liquid 8) Can compound x ever be a solid at 800 degrees according to the diagram? no
