Answer 2

Answer:

If the normal melting point of a substance is below room temperature, the substance is a liquid at room temperature. Solid substance (Benzene) melts at 6°C and boils at 80°C; it is a liquid at room temperature. If both the normal melting point and the normal boiling point are above room temperature, the substance is a solid.
