Answer:
a) At point C : The substance is in the liquid state. At point D : The substance has started boiling . It exists both into the liquid and gaseous states.
b) The melting point (or, rarely, liquefaction point) of a substance is the temperature at which it changes state from solid to liquid. At the melting point the solid and liquid phase exist in equilibrium.
c) The boiling point of a substance is the temperature at which the vapor pressure of a liquid equals the pressure surrounding the liquid and the liquid changes into a vapor. ... A liquid at high pressure has a higher boiling point than when that liquid is at atmospheric pressure.
d) -
