A splinter of wood has a low ignition temperature so, a burning matchstick can produce sufficient heat to attain the ignition temperature of the splinter of wood hence, a matchstick can easily light a splinter of wood. 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.
