When you burn coal, you are burning pure carbon. Wood is primarily cellulose which is a complex sugar containing carbon hydrogen and oxygen.

William, I looked it up and came up with this referring to coals: These have less moisture content and tend to be denser than a natural log, so they burn hotter and longer. ... While forests can burn for months at a time, there is a coalseam fire in German that has been burning since the 1600s.

Both coal and oil are fossil fuels. That means they're formed from organic matter – stuff that was alive on Earth millions of years ago – that was covered by heavy layers of rock. ... Most of Earth's coal originated as trees, ferns, and other tropical forest plants that lived in a warmer time in our history.

Similarities: they are both formed from organic remains and both form under enormous pressures in a sedimentary sequence. Differences: coal is formed from land-based plants in bogs and coastal swamps, while oil and gas are derived from tiny marine organisms, such as algae and phytoplankton.

Although coal is primarily a mixture of carbon (black) and hydrogen (red) atoms, sulfur atoms (yellow) are also trapped in coal, primarily in two forms. In one form, the sulfur is a separate particle often linked with iron (green) with no connection to the carbon atoms, as in the center of the drawing.

Explanation: Coal is a solid, oil is a liquid and natural gas is a vapor (gas). ... Coal is obtained primarily by mining while oil and natural gas are extracted from wells drilled into the earth from land or sea-based platforms. Coal is a complex mixture of many different long-chain hydrocarbons.

Anthracite, or “hard coal,” contains the highest amount of carbon out of all coal ranks (86%-97%)1. ... Bituminous coal, often called “soft coal,” has slightly lower carbon content than anthracite (45%-86%)1. The wide range of carbon content in bituminous coal warrants use for both electricity and steel production.

Burning of coal is chemical change while burning of candle is physical as well as chemical change. coal is naturally available and is carbon based. ... Coal is primarily used as a solid fuel to produce electricity and heat through combustion candle is made of wax.

Candle burns with a flame but coal does not burns with a flame. Also coal is a carbon product and its burning is harmful for environment but candle is made from wax its burning is not as much harmful as burning of coal .

Are Coals Hotter Than Flames? No, given all else being equal, coal has the same potential heat as the wood beginnings, but due to the lack of oxygen and surface area, they produce less heat.

Coal is a sedimentary rock. Coal is altered through biological and burial-thermal processes into different ranks.

Both coal and oil are carbon-based fuels – they're made up mostly of carbon and hydrogen. Coal usually forms from buried tissues of higher plants. ... Oil mostly originated as very simple organisms – such as bacteria, algae and plankton.

The main difference between the formation of coal and petroleum is as follows:-) #petroleum are formed with the deposition of sea animals under high pressure and high temperature whereas the coal is formed with the deposition of plants and trees under high temperature and high pressure.

What is the difference between modern carbon and fossil carbon? We call the carbon in biomass modern carbon, in contrast to the carbon in fossil fuels, which we call fossil carbon.

To be accurate, coal is a mixture of compounds (like water, hydrocarbons etc.) and elements like carbon, sulphur etc. Coal does contain a lot of volatile matter (almost all of them being compounds). Coal also contains some elemental sulfur and small amounts of trapped Nitrogen and Oxygen.

Coal is a black or brownish-black sedimentary rock that can be burned for fuel and used to generate electricity. It is composed mostly of carbon and hydrocarbons, which contain energy that can be released through combustion (burning).

Coal is a Natural mineral whereas Charcoal is a man made mineral. Coal is a natural mineral that is formed under the earth's crust due to the prolonged decay of plant and animal matter due to the heat and pressure. ... As coal contains mainly carbon, the conversion of dead vegetation into coal is called carbonization.
