Sulphur

Sulphur, It starts off as a yellow solid.

On Warming….

….melts to form a runny yellow liquid at 113 degrees Celsius

• This is because the Van der Waals bonds are breaking.

Van der Waals

• Van der Waals bonds are the bonds between the molecules. As the Sulphur gets heated these forces begin to break

• Watch the Picture

Notice a Difference?The Van Der Waals are broken

This is why the Molecules are no longer together

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

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

Finally Everything breaks and the Sulphur becomes a runny liquid again

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.

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