Here's why:

* Molecular Structure: Sulfur exists as a ring-shaped molecule (S8) at room temperature. These rings are held together by relatively weak van der Waals forces.

* Weak Intermolecular Forces: The weak intermolecular forces between sulfur molecules require less energy to overcome, leading to a lower melting point.

Specific Melting Point: The melting point of sulfur is approximately 115.21 °C (239.38 °F).
