Chemie sulphur 0610 Chemie sulphur 0610 Presentation Transcript

  • STRUCTURE & B ODING OF PLASTIC SULPHUR
  • The start:
    • 1. In the begining the Sulphur is solid & yellow.
    • 2. It consists of 8 Sulphur molecules.
  • When heated: 1. When you start heating the yellow solid at 112°C the solid turns into a liquid. 2. This happens because the weak Van der Waals bonds between the molecules are already break at a very low temperature. 3. Now the molecules can move around and we have a liquid. View slide
  • Over 200°C
    • 1. When the temperature rises you can see the liquid in a very red-brown & thick state.
    • 2. That happens because the covalent bonds (bonds between the atoms in a molecular) break and form a Polymer (one long chain).

  • 444°C
    • 1. When the thick, red-brown substance is heated to 444°C you can see a red-brown& now runny liquid.
    • 2. The long polymer chain has broken again so you now have many shorter chains.
    • 3. This allows the chains to move around and we have a liquid.
  • Runny liquid + water
    • 1. Last but not least you put the runny liquid into a glass filled water.
    • 2. The solid liquid cools down and becomes a plastic solid.
    • 3. This happens because the moving, short chains are stopped by the cold water .
