Carbon vs. Coal

Symbol C An abundant nonmetallic element that occurs in many inorganic and in all organic compounds, exists freely in amorphous, graphite, and diamond forms and as a constituent of coal, limestone, and petroleum, and is capable of chemical self-bonding to form an enormous number of chemically, biologically, and commercially important molecules. Other significant allotropes include fullerenes and nanotubes. Atomic number 6; atomic weight 12.011; sublimation point 3,825°C; triple point 4,489°C; specific gravity of amorphous carbon 1.8 to 2.1, of diamond 3.15 to 3.53, of graphite 1.9 to 2.3; valence 2, 3, 4. See Periodic Table.

A natural dark brown to black graphitelike material used as a fuel, formed from fossilized plants and consisting of amorphous carbon with various organic and some inorganic compounds.

A carbon-containing gas, notably carbon dioxide, or a collection of such gases, especially when considered as a contributor to the greenhouse effect

To burn (a combustible solid) to a charcoal residue.

A carbonaceous electrode in an electric cell.

To provide with coal.

(uncountable) The chemical element (symbol C) with an atomic number of 6. It can be found in pure form for example as graphite, a black, shiny and very soft material, or diamond, a colourless, transparent, crystalline solid and the hardest known material. Category:en:Carbon

To take on coal.

(countable) An atom of this element, in reference to a molecule containing it.

(uncountable) A black or brownish black rock formed from prehistoric plant remains, composed largely of carbon and burned as a fuel.

A sheet of carbon paper.

(countable) A type of coal, such as bituminous, anthracite, or lignite, and grades and varieties thereof, as a fuel commodity ready to buy and burn.

A carbon copy.

(countable) A piece of coal used for burning this use is less common in American English

A fossil fuel that is made of impure carbon such as coal or charcoal.

(countable) A glowing or charred piece of coal, wood, or other solid fuel.

Charcoal.

A carbon rod or pencil used in an arc lamp.

(intransitive) To take on a supply of coal (usually of steam ships).

A plate or piece of carbon used as one of the elements of a voltaic battery.

(transitive) To supply with coal.

(informal) carbon fiber.

(intransitive) To be converted to charcoal.

To cause (someone) to receive a carbon copy of an email message.

(transitive) To burn to charcoal; to char.

An elementary substance, not metallic in its nature, which is present in all organic compounds. Atomic weight 11.97. Symbol C. it is combustible, and forms the base of lampblack and charcoal, and enters largely into mineral coals. In its pure crystallized state it constitutes the diamond, the hardest of known substances, occuring in monometric crystals like the octahedron, etc. Another modification is graphite, or blacklead, and in this it is soft, and occurs in hexagonal prisms or tables. When united with oxygen it forms carbon dioxide, commonly called carbonic acid, or carbonic oxide, according to the proportions of the oxygen; when united with hydrogen, it forms various compounds called hydrocarbons. Compare Diamond, and Graphite.

(transitive) To mark or delineate with charcoal.

A carbon rod or pencil used in an arc lamp; also, a plate or piece of carbon used as one of the elements of a voltaic battery.

A thoroughly charred, and extinguished or still ignited, fragment from wood or other combustible substance; charcoal.

A sheet of carbon paper.

A black, or brownish black, solid, combustible substance, dug from beds or veins in the earth to be used for fuel, and consisting, like charcoal, mainly of carbon, but more compact, and often affording, when heated, a large amount of volatile matter.

A carbon copy.

To burn to charcoal; to char.

An abundant nonmetallic tetravalent element occurring in three allotropic forms: amorphous carbon and graphite and diamond; occurs in all organic compounds

To mark or delineate with charcoal.

A thin paper coated on one side with a dark waxy substance (often containing carbon); used to transfer characters from the original to an under sheet of paper

To supply with coal; as, to coal a steamer.

A copy made with carbon paper

To take in coal; as, the steamer coaled at Southampton.
