What is special about coal?
Coal is made largely of carbon but also features other elements such as hydrogen, oxygen, sulfur and nitrogen.
Coal starts off as plant matter at the bottom of water.
Coal is the world’s largest source of energy for the production of electricity..
Is Coal still being formed?
Coal is very old. The formation of coal spans the geologic ages and is still being formed today, just very slowly. Below, a coal slab shows the footprints of a dinosaur (the footprints where made during the peat stage but were preserved during the coalification process).
What is the rank of coal?
Coal rank is the measure of the degree of organic metamorphism (coalification) of a coal, ranging from low-rank peat to high-rank meta-anthracite.
What are the advantages and disadvantages of coal?
Advantages and Disadvantages of Using Coal EnergyCoal energy is an affordable energy source because of the coal’s stable price compared to other fuel sources.Coal is easy to burn.Coal produces high energy upon combustion.Coal energy is inexpensive.Coal is abundant.Coal energy is a reliable energy source.
How is coal used in everyday life?
Coal is primarily used as fuel to generate electric power in the United States. The coal is burned and the heat given off is used to convert water into steam, which drives a turbine.
What can be made from coal?
Non-fuel uses of coal include chemical products such as refined coal tar which is used in the manufacture of chemicals, for example creosote oil, naphthalene, phenol and benzene. Ammonia gas recovered from coke ovens is used to manufacture ammonia salts, nitric acid and agricultural fertilisers.

What is the highest grade of coal?
AnthraciteAnthracite: The highest rank of coal. It is a hard, brittle, and black lustrous coal, often referred to as hard coal, containing a high percentage of fixed carbon and a low percentage of volatile matter.
What is the difference between coal and coke?
Charcoal is a fuel that comes from the incomplete burning of wood. Coke is a fuel that is obtained from the calcination or dry distillation of mineral coal. … It is composed of carbon and has a high calorific value, but it is highly polluting.
What is a disadvantage of coal?
The major disadvantage of coal is its negative impact on the environment. Coal-burning energy plants are a major source of air pollution and greenhouse gas emissions. In addition to carbon monoxide and heavy metals like mercury, the use of coal releases sulfur dioxide, a harmful substance linked to acid rain.
Why do we use coal at home?
A grate full of burning coal would easily go all night without any attention. We had glass doors on the fireplace to help modulate the draft, which allowed us to burn more slowly at a lower temperature and also greatly reduce the risk of carbon monoxide exposure. … Technology has made coal a friendlier home fuel.
