Yes sir is video ko yanha tak dekh raha hai or agae bhi dekhinga

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

Thank You Sir!

Sir sodium bi carbonate dominate fire thats why its mixed with saponin and aluminium sulphate in a fire extinguisher to make foam of carbon dioxide

Tq so much to explain this chapter

Bhaiya LPG bhi gaseous fuel hoga na

Sir hamare exam syllabus me Sound chapter bhi hai. Please jald se jald Sound chapter bhi complete krwa digiye. Aapki videos se bhout jyada help hoti hai sach me. Bhout kam din bache hai exam ko isliye please next video hi ispar bana ki kosish kigiyega.

Good mroning sir.... But examination over ho gye. But mene science ka exma bohot wchha gaya is chapter ke alawa jitne bhi chapters thhe un sabka revision mene kar liya thha aapke videos se.

Legend revision to exam date

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

Hope you make videos for class 9th also in future...

Rapid =eg. Burning of matchstick Spontaneous= forest fire, clothes fire. Explosive=produce heat light sound and release sound...

Rapid combustion-Cotton,matchstick Spoteneous-Forest Explosive- crackers ,bombs

I am not in 8th standard but your videos help me so much in revision....

11:13 Rapid combustion: matchstick Spontanious combustion: Coal dust Explosive combustion: Light

Sir agar electricity ke substance fire 🔥🔥 catch karte hai to hamein water ka use nahin karna chahiye right sir

Thank you so much sir

pls make a term 2 syallbus explantion in one shot (no parts) just before exams for who need to study everything without gettign ditracted and lossing marks

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.
