Question

the ignition temperature of wood is lower than that of paper .why?​

Answer 1

Answer:

It's because paper catches fire faster than wood

Answer 2

The heating of the fuel produces flammable vapour. Paper consists mostly of cellulose, which is purified wood fibres. The paper-making process removes components from the wood that easily produces flammable vapour. Hence the ignition temperature for wood is lower than that of paper.
