what is the effect on potato slices exposed to air
They dehydrate
The effect on potato slices exposed to air is dehydration. When potato slices are exposed to air, the moisture content in the slices starts to evaporate into the surrounding environment. As a result, the potato slices lose moisture and become dehydrated.
To understand this process, you can conduct a simple experiment. Take a fresh potato and cut it into thin slices. Leave some of the potato slices exposed to the air, while keeping the others covered or submerged in water. After a certain period of time, observe the potato slices that were exposed to air and compare them to the ones that were kept covered or submerged.
You will notice that the exposed potato slices appear dried out, shriveled, and may have a brownish color. This is due to the loss of water content through evaporation. On the other hand, the potato slices that were kept covered or submerged will retain their moisture and stay fresh for a longer period of time.
The dehydration of potato slices exposed to air mainly occurs because of the low humidity in the surrounding environment. The dry air draws out the moisture from the potato slices, causing them to dehydrate. To slow down this process, you can store potato slices in airtight containers or place them in a bowl of water to keep them hydrated.
