(a)
Interpretation: The physical state of phenol is to be determined.
Concept introduction:
The boiling point of a liquid is the temperature at which the pressure exerted by its surroundings equals the vapor pressure present at the liquid's surface.
The temperature at which a substance transforms from a solid to a liquid is known as its melting point.
