Answer:
(a) naphthalene balls disappear with time without leaving any solid because naphthalene balls are sublimable substance so they directly convert into gaseous state without leaving any residue.
(b) it is because of the large intermolecular space present between the perfume particles so that's why we can get the smell of perfume sitting several away.
