Question

Paper by itself catches fire easily whereas a piece of paper wrapped around an aluminium pipe does not. why?

Answer 1

The paper by itself catches fire easily because its ignition temperature is low, while a piece of paper wrapped around an aluminum pipe does not catch fire because its ignition temperature rises.

Paper by itself catches fire easily because it attains its ignition temperature .Hence burns.

Whereas,

 A paper wrapped in aluminum pipe does not burn because:

---> Aluminum is a metal and a good conductor of heat.

--->Heat energy supplied is absorbed by aluminum pipe. 

--> Paper never attains its ignition temperature.

--> Hence paper wrapped in aluminium pipe does not burn.

Answer 2

Hey Mate
A very very Happy new year to you

The answer to your question is



A piece of paper wrapped around aluminium pipe does not catch fire easily. This is because aluminium, being a metal, is a good conductor of heat. Therefore, heat is transferred from the paper to the metal and the paper does not attain its ignition temperature.


Hope it helps!!!!!!!
May God bless you on the new day of the new year ND fulfill all ur dreams
