Question

Burn the paper and the piece of wood turn by turn with the help of the candle which substance takes time to burn? why?

Answer 1

Wood takes a longer time to burn.

This is because wood has a higher ignition temperature than paper

Wood also has greater density than paper. The atoms are more tightly held together in wood than in paper. So a lot of energy would be required to break the particles in wood as compared to the particles of paper
