Heat Transfer
Small Potato vs Large Potato
When comparing the heat transfer between a small potato and a large potato, it should make sense that the larger the potato, the more heat transfer required, and therefore the longer the cooking time.

Let’s rationalize that. |
 |
It takes time for heat to transfer through a potato. The potato center has to reach a high enough temperature for a long enough time for it to cook. As a potato cooks, the heat is slowly transferred to the center of the potato. Because the potato does not have as good of heat transfer properties as say a metal does, this process takes time. Therefore the more potato the heat has to cook, the slower the baking process.
