Question

This also implies that a substance will
exist in the solid state only below and in the
liquid state only above its melting point. Thus,
substances ordinarily existing as solids (e.g.,
carbon, aluminium, iron, gold, etc.) have
melting points higher than room temperature.
Similarly, substances ordinarily existing as
liquids (e.g., water, ethyl alcohol, acetone,
mercury, etc.) have melting points lower than
room temperature.​
