Diamonds, coke, coal, graphite, fullerenes
Coal, graphite and diamonds are all allotropes of carbon and are stable at room temperature.
Solid carbon (C) may be diamond, graphite, coal, carbon black etc.
Well to be very upfront diamond is very heated and compressed carbon (coal graphite) while graphite is more "pure" carbon than diamonds
a physical change
Graphite and coal are both forms of carbon, but graphite is a crystalline form while coal is a sedimentary rock made up of plant material. Graphite is used for its lubricating properties and in pencil lead, while coal is primarily used for generating heat and electricity. Additionally, graphite is a good conductor of electricity and heat, whereas coal is not.
Diamond, coal, graphite, coke and buckminsterfullerene are composed primarily of carbon and are insoluble in water.

coal and graphite
Graphite, coal and diamonds are all thought to be products of the decay and compression of vegetable matter from millions of years ago. Diamonds progress from coal.
Both coal and graphite are made of carbon, but in different molecular structures. Diamond is also made of carbon but in a highly ordered crystal structure.
No, modern pencil "lead" is actually made of a mixture of graphite and clay, not coal. Graphite is a form of carbon that is a good conductor of electricity and is commonly used in pencils due to its smooth writing properties.
Graphite is Carbon, the chemical symbol is C. There are many forms of graphite, such as coal, and diamonds. Even the human body contains carbon. It is dug straight out of the earth just like mining coal and diamonds.
South Korea's Natural resources are coal, tungsten, graphite, Molybdenum
carbon
Coal changes into carbon dioxide and other byproducts when burned for energy. It can also be transformed into graphite through a process called carbonization.
No. It is a physical change, because the graphite is still graphite.
