Solution

The collision theory states that for a reaction to occur, it is necessary for the reacting substances to collide with each other. Not only do they need to collide, but they also need to do so with a certain minimum energy called the activation energy.

When you cut potatoes into smaller pieces, you increase the surface area that is exposed to heat. This means there are more potato molecules available to collide with heat energy. This increased number of collisions, combined with the sufficient energy provided by the heat, means that the cooking reaction happens more quickly.

In other words, by cutting the potatoes into smaller pieces, you're increasing the chances of potato molecules colliding with heat energy, thus speeding up the cooking process. This is a practical application of the collision theory.
