Sulphur (S) is an element that can never be overlooked. In the periodic table, sulphur is found in group 16. It is non-metal and is obtained as a by-product after the production of natural gas. In colour, it is bright yellow, and it has an extremely bad odour. Sulphur is frequently found near hot springs and volcanoes.
Heating sulphur at high temperature
- Sulphur starts to melt at 115oC.
- At 200oC, there is a colour change from yellow to red and starts to boil at 400oC.
- Before reaching the boiling point, it starts to vaporize.
- When it is heated above 445oC, it will ignite.
