Physics Wallah is actually so good for teaching and i just love the teachers they teach with so much enthusiasm and explain every process with a easy method, in my school they just show us a video and get over with it, thank you so much pw ❤
pr sir jb aapne uss pani wali baat btayi uss bacche ne kha ki hum sare milkr pani piyenge fir aapne bola ki sb pagal todhi na hai toh fir aapne todhi der baad apne bola ki hum sare milkr forest jlayenge ya katenge toh sb pagal todhi na hai :>:>:>
Bro tube ke andar oxygen nhi hai but normally air me toh hai hi . Bahar se toh dena possible hai ye thori kaha gya hai ki heat agar bahar se mila toh bhi combustion nhi hogi hope you understand😁😁😁
No,, it's not possible because the definition of combustion is :- the process of burning of a substance in the presence of oxygen is called combustion anything cannot burn without oxygen 🙂 i hope you understand
It's not combustion because it is not giving energy and light.........we are just extracting the residues from bituminous powder when it is getting burnt (the heat from candle is heating the test tube surface which is also called conduction)
5:50 It will be again present on earth when we will urine and then that urine will evaporate further causing rain which will again cause the water to be present in its original amount.
bro their are 4 types of coal, peat, lignite, bituminous, and anthracite. there are three types of main coals lignite, bituminous, and anthracite, sir haven't taught to us about peat because it is not a main type of coal
Peat is the first stage in the formation of coal. In the absence of oxygen and under high temperature and high pressure the dead vegetation get converted into organic matter.This organic matter is known as coal
Sir very big confusion for carbonisation aur colaification which term should be used ? How to convince others for this . Bcz ncert no is accepting what to do ?😥
🌟"I really liked the way the video showed the different applications of coal and petroleum. It was interesting to see how these resources are used in everything from power generation to plastics manufacturing. Thanks for making such a informative video!"🌟
No words,as a father i was worried about me child who is studing i class 8 defence labs school ,Hyderabad he is good .I came across PWD recently umaang batch, watching regularly and spellbound by the change your team is bringing in the education system.

25:35 sir Oxygen ke bina combustion ho sakta hai kya???
Bro tube ke andar oxygen nhi hai but normally air me toh hai hi . Bahar se toh dena possible hai ye thori kaha gya hai ki heat agar bahar se mila toh bhi combustion nhi hogi

Oh god!!! Whom to follow? Who is correct?
4
hi buddy, peat is not a type of coal it is just a material made of partially decayed materials
bro their are 4 types of coal, peat, lignite, bituminous, and anthracite. there are three types of main coals lignite, bituminous, and anthracite, sir haven't taught to us about peat because it is not a main type of coal

Ans. Coke.
50:55 Sir, boiling and condensation point is not same CONDENSATION point Is 0°c and BOILING point is 100°c

You are wrong. Condensation and boiling occurs at the same temperature...

Sir very big confusion for carbonisation aur colaification which term should be used ?
How to convince others for this .
Bcz ncert no is accepting what to do ?😥
i think we should just write what school tells us but we should understand this instead.
You should use both as it well benefit you in your answer

The slow process of conversion of dead vegetation into coal is called carbonization
Well i m in 10th😂 Sunil sir is best for 8,9 and 10th❤

Right sis
Haan our hame marks cut kara jayga just bcz we wrote the correct answers... Mere exams abhi 2 -3 dino me exams shuru hone wale hai our mujhe confusion ho raha hai ki me ye wala answers likhu ya ncert se ki tharah likhu
U do not take risk and write according to tye tb itself why to loose marks
Sir in google also it is showing slow process of conversion of wood into coal is called carbonization .
I'm literally confused what to write in exam 😢🤔
that is my doubt too, if we write coalification in my exam our teachers will say you have to follow the NCERT
Coalification ka speed of conversion is slow , (slow process of conversion of peat into coal I'd o called coalificatwrotedjejg
bhai carbonisation likho because ncert me ekdam theek likha hai because even google says its a slow process
PW best teacher in the world ❤️❤️
Great class i learn all about this chapter then i will crack exams
Sunil sir science ko ham nhi science hame enjoy krti hai,😂😂
thank you sunil sir whenever i not understand chapter i watch physics wallah video
But sir what about our exams? What terms should we use 🥲will it would work if we write colifiaction instead of carbonisation ?
That's my question too.
Use carbonisation because it's available in our ncert book
Bhai carbonisation use Karo ye coalification likhoge to lafda hoga 💀
