Tony Peek took a rather boring animoto from an earlier post and produced a vibrant remix with cool sounds and sound science.
Sulphur movie by Tony Peek (small)
Greast effort Tony.
Shardae has a clever model for changes occurring at the molecular level and explains it all beautifully.
Axel takes a very direct approach with his presentation but it covers the main points. Well done Axel.
Boiling sulphur quenched in cold water produces a different form (allotrope) called plastic sulphur because of its elastic nature.
Different forms of the same element are called allotropes. Diamond and graphite are allotropes of the element carbon.
Produce a powerpoint presentation a short video or poster to explain the changes in sulphur observed as it is heated up to its boiling point. Think about the particles that are present at each stage. What are the forces between them and how does this affect their properties (in particular viscosity) Here are some key points.
