When sulphur powder is heated to over 400^oC the following changes are observed:-
At 113^oC it melts into light brown liquid. The liquid then darkens to become reddish-brown
and very viscous at 160^oC. Above 160^oC the liquid becomes almost black. At the boiling point the liquid becomes mobile. Explain these observations

---

– At 113^oC consists of S₈ rings that flow easily;

- Darkens due to breaking of S₈ rings and forming long chains consisting of thousands of atoms. The chains also entangle;

- The long chains consisting of thousands of atoms. The chains also entangle;

- The long chains break near boiling point to form shorter one.
