What is Coal Tar ?

Coal tar is a black fluid of tremendously high viscosity when coal is carbonized,

Coal tar is among the by-products which manufactured coke or gasified to make coal gas.

Coal tars are compound and variable mixtures of phenols, polycyclic aromatic hydrocarbons (PAHs), and heterocyclic compounds.

Paracetamol is the only coal-tar derived analgesic which is still in use today, but industrial phenol is now usually synthesized from crude oil rather than coal tar.

Effectiveness of Inorganic Coal

Mineral coal is used in producing steam power to drive railway trains, Steam-ships and Steamers.

Steam-power is produced from water boiled by mineral coal. Electricity is easily manufactured from coal by planting thermal stations near coal mines.

Synthetic petrol is manufactured from mineral; coal through a kind of chemical process.

Types of Coal

Coal is a multifaceted resource which differs in composition even inside the same deposit. There are four different types or ranking based on various levels of coal with differences in energy output as a result of increased temperature,pressure & time

Lignite is a brownish-black coal with great moisture and ash content and the lowest heating value of the four types of coal. It is used for generating electricity.

What is Coal ?

Coal is a combustible sedimentary rock composed generally of carbon and hydrocarbons.

Coal is non-renewable resource which is the most abundant manufactured fossil fuel in the United States.

Coal is the leading source of energy for the generation of electricity all over the world, also anthropogenic sources of carbon dioxide releases.

Coal act as abundant resource that has been used for thousands of years to yield energy, mutually in the form of heat and electricity.

How is Coal Formed ?

Since the 13th century coal is derived from the Old English term col, which means "mineral of fossilized carbon".

Coal consists of high content of carbon and other elements like, sulfur, hydrogen, oxygen, and nitrogen.

Coal is a naturally black sedimentary rock occurring in rock strata in layers or veins called coal beds or coal seams.

Anthracite coal is the solider form of coal, can be considered as metamorphic rock because of later exposure to high temperature and pressure.

What does Coefficient of Friction Mean?

What does Coefficient of Friction Mean ? Let us check it out the definition of coefficient of friction to know more about friction.

Meaning or Definition of Coefficient of Friction are :

Coefficient of friction is the value which show the relationship between the two objects and the normal force between them.

It is the ratio of the force between the object and the surface to the frictional force which resists the movement of the object. 

What are the Types of Friction ?

What are the Types of Frictions ? Let us check it out some of the types of friction to learn more about friction. This type of frictional force is responsible for wear and tear of two bodies, Following are some of the types:

Types of Friction are:

  1. Static Friction
  2. Kinetic Friction
  3. Rolling Friction
  4. Fluid Friction

Static Force comes into action when a body is forced to move along a surface but the movement of the body does not starts. Example Pushing on a wall
