  • Q:

    If one follows a line separating phases in a phase diagram and examines a substance at that particular pressure/temperature, which of the following can be guaranteed?

     

    A

    At any given point, there will be 50% of one phase and 50% of another phase of the substance.

    B

    If the line separates solid and liquid and has a negative slope, the solid is more dense than the liquid.

    C

    All three phases exist to some degree along every point of the line.

    D

    Along the curve which separates the gas phase from other phases, decreasing pressure will result in a predominance of gas molecules in the substance.
