Recognize that hydrogen gas is very light and rises rapidly in air, if gas is not burning, it may collect in the upper levels of structures, creating an explosion hazard. Auto-ignition temperature: 1058 ˚F (570 ˚C).
Only few trs teach in english this is why less of the Student attend the class you should be teaching in english not hindi there are many students who want to study from South India too...like me....this is not the first time...
I don't know but why I am thinking that she is the best teacher...I have ever seen for science..because her explanation for each and every topic was fablous😊❤
No, substance reacts with oxygen. So imagine you are turning on your gas stove, the LPG (LIQUID PETROLEUM GAS) is released and you give a little heat in order for the reaction to occur. The heat reacts with the LPG and oxygen acts as a fuel. Meaning the fire (heat and light) needs oxygen to keep burning. It's very complex and we would learn about it in higher classes. If there is anything wrong about my explaination, please tell me because...I am also an 8th grader😅

Maam I have question does oxygen burn🤔🤔🤔🤔🤔🤔
No, substance reacts with oxygen.
So imagine you are turning on your gas stove, the LPG (LIQUID PETROLEUM GAS) is released and you give a little heat in order for the reaction to occur. The heat reacts with the LPG and oxygen acts as a fuel. Meaning the fire (heat and light) needs oxygen to keep burning. It's very complex and we would learn about it in higher classes.
If there is anything wrong about my explaination, please tell me because...I am also an 8th grader😅
If you are asking if oxygen is combustible, it is not combustible on its own.
No , ofc
Thankyou mam it was a great session😃
Homework Answer:- combustible fibre :- rayon
Mam i have an question that what is difference between combustion and burning
