I day before I m seeing 😂😂
Me seeing when only 10 minutes are left
37:04 thank you sir
There are 3 types of combustion
Rapid - Matchsticks
Spontaneous - Forests, Coal Mines
Explosive - Fire Crackers
Jo sir ke padhai se khush hai wah like kare
Rapid combustion=Produce Heat and energy in very large amount in a short period
Spontenioun Combustion=A substance burn by its own without the help of external heat
Explosion=A substance producing Heat,Light,sound in very large amount
Outstanding 🔥
Sabhi legends nahi hote kuch logon ka toh exam bohot doer hai par ek ne legend likh diya uska piche sabhi likhe rahen hai i am legend 😂😂😂😂 itne achi baat kahi hai fir bhe 0 likes why????????????😢😢😢😢😢💔💔💔💔💔❤️🔥❤️🔥❤️🔥❤️🔥

Thanks sir for this type of revision video
I am also from haryana 😅😅😅
Yes
Nice explanation....most trusted platform.
I am new on your i will suggest my friends to watch your videos.
A lots of love and support
😊Rapid _ very fast burning
Spontaneous _ without any apparent cause
Explosive _ large amount off heat sound and light energy amount off gas
Rapid - matchstick
Spontaneous - coal dust, forest fire
Explosive - fire crackers
There are 3 types of combustion :
Rapid combustion :- Matchsticks
Spontaneous combustion :- Forests, Coal Mines
Explosive combustions :- Fire Crackers
namaste sir aap acha padate i like your teaching. Thanks!
Rapid combustion - Petrol Diesal and LPG etc.
spantenous combustion - Red Phosphorus , white phosphorus etc.
Explosion - Bomb and firecrakers etc.

Tankyou so much ❤
Welcome dear 🤗
Rapid combustion eg: petrol, diesel and matchstick
Spontaneous eg: Forest fire, mines and factory
Explosive eg: Fire cracker, dynamite and nuclear bomb
Rapid combustion - kerosene and natural gas. spontaneous combustion- forest fire and cool mining. Expolsive combustion- fire crackers.
There are three types of combustion -
1 ) Rapid combustion - burning of matchstick
2) spontaneous combustion - forest fire
3) explosive combustion - firecracker
Rapid combustion:- whenever an substance burnt 🔥 in a rapid speed and produces heat and light energy
Spontaneous combustion:- the type of combustion in which a material suddenly brust into flame by giving lots of light and energy
Explosives combustion:- a large amount of gas formed in the reaction is lubricated . Such a reaction is called explosives combustion
There are three types of combustion:
Rapid combustion: matchstick
Spontaneous: coal mines, forest fire
Explosive : fire crackers
Sir tomorrow is my exam and today i was learning this i was worried about the exam but since i watched you video i am feeling confident
Thank you sir for your help
Rapidly combustion : Petrol
Spontaneous combustion : Volcano Explosion
Explosive combustion : TNT
Rapid cobustion: matchstick.
Spontaneous combustion:white phosphorus.
Explosion 💥:Suthli bomb 💣.
Rapid combustion: matchstick

Welcome dear 😃
Tyes of combustion
(1) Rapid combustion very fast
for example burning of matchsticks
(2). spontaneous without any apparent for example first fires. and coal miners. what is coal miners= coal dust
(3) Explosive large amount of heat and light sound. gas evolve
11:13 Rapid combustion: matchstick
Spontanious combustion: Coal dust
Explosive combustion: Light
This video is very best ❤❤❤❤
Rapid combustion
In this type of combustion a large amount of heat and light is released in a very short period of time
Spontaneous combustion
In this type of combustion a substance catches fire on its own
without the application of any external heat
Explosion
In this type of combustion there is a sudden release of heat and light. It is also accompanied by production of sound and so large amount of gas
Example -- firecrackers
11:19
Sir what is difference between spontaneous combustion and rapid combination
Bro rapid combustionneeds and external source to burn but spontaneous takes place on its own
@@DEEPANSHUSHARMA-qi4oh thx bro but today was my exam so abhi PT 2 exam me batna abhi to mai science ki textbook khula ga bhi nahi
You are the best teacher of science
Sir cumbustion and flame ka full video laeye . Aap bs revision laaye hai. Full chapter ka video upload kijiye😊😊 class 8
Rapid combustion : matchstick
Spontaneous : forest fire
Explosive : fire crackers
Gjb sir❤❤❤❤❤❤❤😊😊😊😊😊😊😊🎉🎉🎉🎉
Combustion are of three types rapid combustion burning easily and fast of speed for example a matchstick spontaneous burn by itself for example forest fires and coal mine explosive in explosive there is a large amount of heat and energy and gas is released for example firecrackers
rapid combustion: the combustion which acts very fast, eg: petrol on fire.
spontaneous: which happens without any apparent cause, eg: forest fires.
explosive: which gives off large amount of fire, heat, gas, sound and light, eg: fire crackers, granade.
Very nice 👍🏻
thank you sir because of you i will get good marks
@@itznotlazyplayz7165I don't know about that tho
Rapid combustion=burning of a matchstick

Spontaneous: forest fire, coal mines, white phosphorus
Explosive: fire crackers
Thank you sir
and
legends will watch this video before exams
17:58 yes sir
Hi sir im from bihar you are breaking up
Spotnous-coal mine
Explosion-fire cracker
Rapid-matchstick

Sir agar ideal fuel exist he nahi karta tho ye term kaha se aaya hai..?
Ideal ek word hai just.... apko science mei bohot sari terms milengi jinme ideal word laga hua hoga...
Jese Ideal gas, Ideal Shapes, Ideal Body, ideal fuel etc....
Ideal matlab hota hai perfect in every thing
May I ask a doubt pls tell me may I?
Rapid combustion _very fast any object burn for ex petrol or match stick
Spntaneous_any object burn without any apparent cause for ex forest fire or in coal mine place because their coal dust found that cause fire very easily
Explosive_large amount of energy released for ex light sound and large amount of gas released for ex fire crackers
Nice sir thank you so much
Rapid combustion -- a type of combustion in which substance rapidly react with oxygen and produce heat and others energy
