The graph below shows the changes in viscosity in liquid sulphur on heating. Use it to answer the questions that follow.

Explain what happens in the region:
i)XY
ii)YZ

---

i)XY – viscosity increases because sulphur atoms join to form long chains which entangle increasing viscosity
ii)Viscosity decreases because the long chains break to short ones as temperature nears boiling point
