Question

Explain why naphthalene balls kept in stored clothes in our homes disappear over a period of time?

2. This is because naphthalene balls convert from solid to a directly gaseous state means sublimation occurs.
3. The naphthalene balls keep on forming naphthalene vapors slowly which disappear into the air.
