NCERT VIII - Sciences Give reasons. (c) Paper by itself catches fire easily whereas a piece of paper wrapped around an aluminium pipe does not.

Answer»

n temperature of paper is very low. When we try to ignite a paper, all the heat is absorbed by the paper and when it reaches its ignition temperature, it catches fire.But when the paper is wrapped around a ALUMINIUM PIPE, aluminium being a GOOD conductor of heat, absorbs most of the heat and it takes more time for paper to reach the ignition temperature. So it doesn't catch fire easily.
