At higher
pressures the freezing point and boiling point both increase for
this chemical. The slope of the between the solid and liquid
phases is positive.
If the line separating solids and
liquids was negative, the freezing point would decrease as the
pressure increased.
The line separating the liquid and gas
phases is always positive.
The Correct Answer is A. |
