Solution

The reason why a splinter of wood burns faster than a log of wood can be explained in a few steps:

  1. Surface Area: A splinter of wood has a larger surface area compared to its volume than a log of wood. This means there is more wood in contact with the oxygen in the air, which is necessary for combustion.

  2. Heat Penetration: In a larger piece of wood like a log, the heat from the fire has to penetrate deeper into the wood to maintain the combustion process. This takes more time than in a splinter where the heat can quickly reach all the wood.

  3. Moisture Content: Larger pieces of wood like logs often have more moisture than smaller pieces like splinters. This moisture has to be evaporated before the wood can burn, which takes energy and therefore time.

  4. Ignition Time: Smaller pieces of wood require less heat energy to increase their temperature to the ignition point. Therefore, they catch fire and burn faster.

So, in summary, the splinter of wood burns faster than a log of wood due to its larger surface area to volume ratio, quicker heat penetration, potentially lower moisture content, and faster ignition time.
