Can you burn a piece of wood by bringing a lighted matchstick near it explain?

Answer No we cannot burn a piece of wood by bringing a lighted matchstick near it. When a lighted matchstick is brought near a piece of wood it does not start burning because the ignition temperature of the wood is higher than a piece of paper. A matchstick can light a tiny splinter of wood but not a big log of wood.

Why does a log of wood not burn by a matchstick but a paper does?

A substance burns only when it reaches its ignition temperature, as paper has a lower ignition temp. than that of log of wood, hence can be burned by a matchstick, but a log of wood needs more energy to reach the ignition temp, hence cannot be burned by a matchstick.

Why does a matchstick not burn of its own?

A matchstick does not catch fire and burn on its own at room temperature because the ignition temperature of matchstick is higher than the room temperature. … If kerosene is heated little it will catch fire easily because kerosene oil has a comparatively low ignition temperature which is reached even on little heating.

Hence a matchstick burns on rubbing it on the side of the matchbox.

Is a matchstick a fuel give reason?

On rubbing the match stick in the rough surface, the friction converts this work into heat. The heat raises the temperature of the chemical present on the match stick head to its ignition temperature. Due to this the chemical substance catches fire and the match stick starts burning.
