napthalene has a property to sublime. these balls turn into vapour because the intermolecular force is very weak.

 because it directly change into gas

This is due to the property of sublimation. Some solids do not exist in their liquid form; instead they directly evaporate from their vapour forms. Naphthalene is among those solids that show the property of sublimation.
So naphthalene balls disappear after some time due to the property of sublimation.

AS NAPHTHALENE BALLS HAV THE TENDENCY OF SUBLIMING WEN EXPOSED TO ATMOSPHERE THEY DISAPPEAR AFTER SUM TYM.

due to sublimination

Naphthalene undergoes sublimation easily i.e., the change of state of naphthalene from solid to gas takes place easily. Thus, naphthalene balls disappear with time without leaving any solid.Following things also show this property:-

1)AMONIUM CHLORIDE

2)IODINE

3)CAMPHOR
