Mam I am from tamil nadu and I cant't understand hindi so pls avoid speeking in hindi often cuz at times any important stuff comes u change it to hindi and I get confused so pls mam a kind request mam thank you so much mam
40:29 we can pause and take screenshot
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...
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
mam how to find ignition temp. of a substance ??
Sweet boy 🍬🍫🍪🍦🍨🍧🥧🍬🍨🥧🥟🍱🍚🍧🥟🍕
Yes mam
22:03 style of saying ok 😅😅😅😂😂😂🤣
Okay?🤓🤓😂😂😂😅😅😅
🤣🤣🤣
🤣🤣
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
thank you for giving answers for my doubts
Thank you mam it helps me to get good marks in exams
Petrol ignition temperature is 280 Celsius
Wowwww ma,am u can understand very nicely....thank you so much ❤️😍😘 ma,am
41:00 I literally laughed on your expression while raste pe aa jayenge
26:58 combustion and flame
thanks

Yes
yes we can
No we cant...we can only use mobile phones and ipads to burn fire
@@pxrth1v What A joke :)
U examplaided ignition temp very deep n nice
Hi
Ma'am you teach very nicely , I love your teaching and I understand everything 🤗🥰👋💫
29:33 yes mam aag ko bhi kuchh khaney ke liye chahiye 😂😂😂

Namibia man you are my favourite
Mam please can you make classes on reasoning also please mam
Mam your teaching is very nice 😊!!
I love your teaching 🤗😁
Thanks miss for teaching us so nicely that l can understand quickly ,,😃😃
Realy
you are the great teacher
33:40 but water also has oxygen in it.....will it not help the fire...pls answer me mam
even i asked the same question to my teacher . she told that the oxygen form in water is uncumbustable, oxygen should only be in gas form. the constituent elements of a compound differ from the element itself.
here water - H2+O=H20
H- EXPLOSIVE GAS
O- CUMBUSTION
BUT water extinguishes fire.
SOOO... you get it.
not the best explaination, becuase even i am in 6th
short answer- no
long answer- when hydrogen gets mixed with oxygen the result is oxygen
hydrogen is flamable but oxygen is not
yes oxygen is a fuel and supports combustion ozugen cant be burnt
if you are confused :
a candle will burn only if there is oxygen but the candle wont burn the whole oxygen constitute in the air that will put the whole world on fire.
so where were we? yes, hydrogen combines with oxygen the result is water, when the atoms of hydrogen and oxygen get linked they make a molecule with completely diffrent properties You can't burn pure water, which is why we use it to put out fires instead of starting them
but you can burn hydrogen
@Utkrisht Gandhi sorry it was an error but before replying read further bruh
Thanks so much for your help
Amazing
Mam you are very good teacher thanks for teaching mam ✍✍✍✍✍

@@VedantuJunior mam sir ne padhaya h vochapter ap padhaiye plz
Mam what does inflammable substances mean ??
Inflaming substances mean which can not produce flame after burn because they burnt completely and no particle vapourise after burnt.

Yes mam you tech very well
Thank u mam u make our study easy
All the best
@@VedantuJunior thanks mam 🤗🤗
26:48 class 8th Start 👍🏻
ma'am what is calorific value of flame? If anybody knows please replay.....
Hi
Calorific value of a fuel is the heat liberated when one gram of fuel burns completely in oxygen
SI unit is joule per kilograms
Okay👍
@@ArtiSingh-os9yi okay, thank you a lot.
Your teaching style is superb
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.
Nice teaching
My all doubts are clear Ma'am ❤️❤️❤️❤️❤️❤️❤️❤️❤️❤️❤️❤️
Thank you Ma'am 💞💖👍🏻👍🏻👍🏻👍🏻👍🏻
Nice explanation 😀
28:20 Mam I watch video on Mr Indian hacker he make fuel from plastic
yes, but we can use plastic as fuel just after burning i.e wood can be burnt and used as charcoal but you can't put 50 plastic bottles in a steam train engine, but after all those processes which Mr Indian hacked did can make fuel...but it is not it's original form
I am freind of him i meet him
@@rameshnarkhede2513 so
Thank you ☺️ mam 😁
Nice explained 😁
I understand this chapter issly because of your help😁😁😁😁😁😁😁👍🏻👍🏻👍🏻👍🏻👍🏻
The sensation of hotness called heat 😀 simple
Really understood everything 🥰🥰🥰🥰🥰🥰
Thank you🥰 mam
Mam this video is helpful for me mam but you are speaking in hindi so i cannot understand your words
S mam say in Kannada or English
Do we hv to give fees for telegram classes???
No
No
No ma'am laboratory thermometer is generally used to to measure the outside temperature not a liquid thing😊😊
You are incorrect lab thermometer is used for lab in outside it use only maximum -minimum thermometer is uesd only
😂😂

Nooo funny this is very.v sirrish
What was funny yaar
Ma'am, I want to ask that do we use fuel while lighting up a matchstick... Because according to me we just need heat and 02
Doesn’t matchsticks have a type of chemical present in the red part
