In rapid combustion you can even add that it happens with the help of a fuel that means you need to burn the fuel whereas in the spontaneous combustion you need not need a substance to burn it ,it will burn as soon as it is in the room temperature
41:00 I literally laughed on your expression while raste pe aa jayenge
Mam please can you make classes on reasoning also please mam

Awesome video , understood all my doubts and queries
Amazing
30:00 mam but the pen is made up of plastic and plastic is non-combustible material so how you can say that pen can burn rather it can melt at ignition temprature
No it just a example
Thanks..Understood the chapter nicely...but didnt find the topic of fuel efficiency and burning of fuel leads to harmful products...but loved the class...
Lots of thanks 😊 mam.

29:20 mam how is fire formed when we strike two stones together. There is no fuel in there..... pls confirm !! :-)
There is a spark and fuel is the dry grass
Rubbing those two stones produces spark and when it is near the dry grass as there is less moisture it catches fire
Because of friction...

Okay?🤓🤓😂😂😂😅😅😅

Yess
Ma'am what is different btw the incomplete or complete combustion you didn't explain this
in complete combustion - the fuel or substances which burns completely in incomplete combustion - the fuel or substance which burns incompletely if u find any mistake then sorry as I m a student also .... [in English also]
in complete combustion the flame is in blue colour and incomplete combustion the flame is yellow any mistake so sorry
Complete Combution - occurs when there is plenty of supporter of combution or O2, it burns Completely producing CO2, heat and light and leaving on residue behind.
Incomplete Combution - occurs when there isn't sufficient O2, it gives out smoke,soot etc and CO.
Very nicely explained 👌👌🥳
can we use wood or petrol as a fuel for flame
yes
Yes
yes we can
No we cant...we can only use mobile phones and ipads to burn fire
@@pxrth1v What A joke :)

Inflaming substances mean which can not produce flame after burn because they burnt completely and no particle vapourise after burnt.
