Anthracite is a hard, compact variety of mineral coal that has a high luster. It has the highest carbon content, the fewest impurities, and the highest calorific content of all types of coals, which also include bituminouscoal and lignite.
Anthracite is a type of coal that is known for its high carbon content, low moisture content, and high energy density. It is considered the highest grade of coal due to its purity and high heat output. Anthracite is a hard, shiny, black rock that burns cleanly with little smoke or odor. It is typically used for heating homes and buildings, as well as in industrial applications such as power generation and steel production. Anthracite is more rare and more expensive than other types of coal, but it is valued for its efficiency and cleanliness when burned.
Tomorrow i am having my science exam and this video was just soo good, i loved it and it was soo soo helpfull ❤thanku guys for making such productive videos ❤a great applause for you 👏👏
Anthracite, also known as hard coal and black coal, is a hard, compact variety of coal that has a submetallic lustre. It has the highest carbon content, the fewest impurities, and the highest energy density of all types of coal and is the highest ranking of coals.
It is the hardest coal and has semi metallic lustre. It is the purest form of coal which contains about 94-98 % carbon. It's moisture content is very low and thus it is also known as smokeless coal.
MA'AM, PLZ REFER TO NCERT CLASS 8 UNRATIIONALISED TEXTBOOK; IT SAYS, IN CHAPTER 3, SYNTETHIC FIBRES AND PLASTICS, that nylon is made from coal, water and air

mam i have a doubt that in my book of ratna sagar it is written that synthetic fibres are obtained from coal tar so nlon is also synthetic so why wrong please help me
I'm Vivek Suyal it's my sister name written here 👈 Not seen live my mean premiere but liked and subscribed and the answers of questions are 1. Nylon 2. Absence of air
Please bring more sessions like this 🎉🎉 ,, concept bites cleared all my questions ,, And in My school in term 1 chapters that are coming are:- Microorganisms Synthetic fibres Metals and non metals Coal and petroleum Cell structure and functions Force and pressure Friction Thanks for these series of concept bite ❤❤😊
HOMEWORK:- What is Anthracite? Answer:- Anthracite is a hard, lustrous and black in colour. It is the most expensive and high rank coal. It has the highest calorific value and is the cleanest form of coal. It's carbon content is more than 80%.
Anthracite is the type of coal ,hardest coal about 92 to98%carbon and good type of coal ❤😂i hope its helpful for you all if you want ro add any other point then add it😮

@@anweshaanandita7753 yep they are but very less . I mean it's not like what it was before
I too hope so
@@Dreamer_283. oh I didn't know that as I am new
But what is this concept bites there should be one shot videos na
anthracite is a form of coal which ha 90% of carbon and very low moisture and volatile present in it , it is the best type of coal

anthracite coal of a hard variety that contains relatively pure carbon and burns with little flame and smoke.
Anthracite is a type of coal found 6000m deep in Earth. It is the best quality of coal contains above 90% of carbon content.

Coal is hard black combustible mineral that consists mainly carbon .It is found in deep coal mines.,under the surface of earth.
Hii mam thank you 😊 for a great session
