The plots below represent partial phase diagram representing vapor pressure vs. temperature curves for diethyl ether (CH3CH2-O- CH3CH2), ethanol (CH3CH2-OH), liquid mercury (Mercury is the only liquid metal), and water, not necessarily in that order.   Answer the following questions based on the diagram:  a) which is the most likely vapor pressure vs. temperature curve for diethyl ether (CH3CH2-O- CH2CH3)? b) Arrange the four compounds in the order of increasing boiling points. Use the names or the formulas to show your answer.
