Sulphur starts as a yellow solid that melts into a runny yellow liquid at 113 degrees Celsius as the van der Waals bonds between molecules break from heating; continued heating leads to a highly viscous substance until more energy breaks the covalent bonds and turns it into a runny liquid again, similar to how a class of students might behave when heated from a solid to liquid state.

1. Sulphur

2. Sulphur, It starts off as a yellow solid.

3. On Warming….

4. ….melts to form a runny yellow liquid at 113 degrees Celsius This is because the Van derWaals bonds are breaking.

5. Van der Waals Van derWaals bonds are the bonds between the molecules. As the Sulphur gets heated these forces begin to break Watch the Picture

6. Notice a Difference?The Van Der Waals are broken This is why the Molecules are no longer together

7. Continued heating leads to a highly viscous substance that cannot be poured from the test tube.

8. Covalent bonds between atoms are strong ( water doesn’t break down into hydrogen and oxygen when you heat it to make a cup of coffee before school). It takeas a lot of energy to break covalent bonds

9. Finally Everything breaks and the Sulphur becomes a runny liquid again

10. Think of it like a Junior class. First they are a solid, heat it up in summer and they might melt. Give some more heat and they can no longer stand. Finally, Superheat them until they soil themselves and they will become a nice runny yellow liquid.

12. Or maybe they will just go werewolf and drum you to death
