  • There are several allotropes of carbon of which the best known are graphite, diamond, and amorphous carbon.[12] The physical properties of carbon vary widely with the allotropic form. For example, diamond is highly transparent, while graphite is opaque and black. Diamond is among the hardest materials known, while graphite is soft enough to form a streak on paper (hence its name, from the Greek word "to write"). Diamond has a very low electrical conductivity, while graphite is a very good conductor. Under normal conditions, diamond has the highest thermal conductivity of all known materials. All the allotropic forms are solids under normal conditions but graphite is the most thermodynamically stable
  • Don't it have something to do with the recipe?
  • Actually, all living things on this planet contain carbon. Life on other worlds could be based on silicon. Carbon is only one element in the composition of living things. Complex chemical reactions are necessary between a variety of elements before the components of life are present.
  • ... because life is not carbon & carbon is not life ... ... carbon is just one of the many ingredients making up living things ...
  • Just because something contains carbon, it doesn't mean it has to be alive.
