Why is it easier to start a fire with kindling rather than with large sticks and logs of the same kind of wood?

Explained

Explanation:

Kindling can lead to higher temperature in shorter time than Large sticks or logs. In Kindling the surface area per unit mass is greater hence, heat transfer is quicker so, in less time it reaches its ignition temperature

Whereas in a log of wood heat is not as concentrated as in kindling as it conducts to a greater mass and hence, they are slower to reach the ignition temperature.
