✮Reason✮
➙ As in this process , sublimation takes place, that is the change of solid to gaseous state without entering into the liquid state, these balls keep on forming naphthalene vapours and they disappear by giving us a good and pleasant smell. Sublime is the one which is being converted to gas and it undergoes sublimation and the substance or the product which is formed is termed as Sublimate. Sublimation is used in purifying compound and kept under clothes and tables, sinks for smell and to avoid insects, and others. It is done on it's own, no heating or cooling is done here. Sometimes heat is been added.
✬Deposition is the process in which gas is been converted to solid without entering into the liquid state on cooling.
