Question

Why does food coloring penetrate a smaller potato cube faster than it penetrates a larger potato cube?

Answer 1

Answer: (C) The larger cube has more volume, so the food coloring takes more time to soak in.

Explanation: Since the potato cube was very small, it absorbed the dye faster than the big potato cube because of its small surface area compared to the bigger cube. (PS: I've done a experiment about this topic before)

Answer 2

Answer:

Option D, he smaller cube has more surface area compared to volume, so there are more places for the food coloring to soak in

Explanation:

The surface area is the major key factor that effects absorption of any substance by  other substance.

Here, the surface area to volume ratio of a smaller cube is higher as compared to that of a large area.

Thus, the coloring particles find more area to absorb for a smaller cube than a larger cube and hence food coloring penetrate a smaller potato cube faster than it penetrates a larger potato cube

Thus, option D is correct
