One day Radha's mother was complaining that the woollen and silk clothes which she has stored in
closed steel trunks had been partially damaged by some tiny insects. When Radha heard this, she
asked her mother to place some small, white balls of a particular material inside the clothes before
storing them. Her mother did the same. When she opened trunks again after six months, she found
the stored clothes had remained safe this time. At the same time, she also noticed that white balls had
become much smaller in size.
1) What is the material of small white balls placed inside the clothes?
i Why do small white balls become smaller and smaller with time?
111) Name one other material which shows this process.
iv) Draw a neat and well labelled diagram to show the experimental laboratory setup of this
process.
