Below is a sketch of graph showing the change in viscosity (Ease of flow) with temperature when solid sulphur is heated. Describe what happens to the sulphur molecules when is heated from 150oC to about 200oC.

The molecules which were in form of a ring open up to give chained molecules (S8). This entangles each other reducing the flow of molten sulphur and increases its viscosity. Further heating breaks the chains. Short chains now tangle less decreasing the viscosity
