3. Name and define the process which is responsible for the movement of the substance mentioned in answer (b).
4. Write specific names of the processes which occur in beakers B and C. [kinds of processes defined in answer (c)].
5. Would there be any difference in the weight of the potato cylinder in beaker A after 48 hours? Give reason.
