♥ ACE PROJECT = Carbon (Solids)
Title: Carbon (Solid)
Slide 1: What Is An Allotropes?
From what I have researched on, I know that allotropes are compounds that exists in forms with different chemical structures. Some common examples are fullerene and carbon (diamond, graphite)
Slide 2: How to form diamonds
120km to 200km below our feet, diamonds are formed. Rocks in the upper mantle of the Earth melt due to high temperatures. The carbon from these rocks is forced lower into the earth where it finally condenses into new rock. If the temperature and pressure is just nice, the carbon will form diamonds. Then, the diamonds rises to the surface of the Earth.
Slide 3: How to form graphite
In graphite, the carbon atoms bond together in layers, with each layer being parallel to the next and previous one. These layers allow graphite to flake apart, like when you use a pencil to write on a piece of paper.
Slide 4: How to form fullerene
A fullerene is formed when “carbon containing materials are burned with limited oxygen”. The fullerene tube structure is often referred to as a nanotube.
Slide 5: Conclusion
Diamond-edged saws cut stone for masons. Graphite electrodes allow electricity to jump between them, creating light. Fullerene molecules preserved noble gas molecules; These noble gas molecules then give testimony to a meteor impact that occurred in millennia past. These are just some uses I got form the internet.
