Question

A student investigated the effect of size on the movement of molecules.
He cut three different sized cubes from a block of clear agar jelly.
Cube A was 2 × 2 × 2 cm. Cube B was 1 × 1 × 1 cm and cube C was 0.5 × 0.5 × 0.5 cm.

The student wore safety glasses and placed the cubes in a beaker of red dye solution for five minutes.

He then poured the solution into another beaker, washed the surface of the cubes and dried them with blotting paper.

Figure 1 shows what the cubes looked like before and after.
