Sublimation is the direct transformation of a compound (or element) from the solid phase to gas phase.
Under ordinary conditions, sulfur has a low enough vapor pressure that it doesn't sublime to any appreciable extent. Naphthalene, on the other hand, does ... that's one of the reasons it's used in moth balls.

Do naphthalene balls sublime?
Yes, naphthalene balls have the property of sublimation. This means that they transition directly from a solid state to a gaseous state without passing through a liquid state. When exposed to air, naphthalene balls slowly vaporize and release a strong odor.
How naphthalene acts as a sublime solid?
Naphthalene is commonly found in mothballs, which in recent times has been appearing as an abused substance. The naphthalene sublimates, meaning it turns directly from a solid to a gas, which is used for huffing. This has led to some slang terms about mothballs being sublime.However, naphthalene is anything but sublime. It is now being learned that it is an addictive substance. It makes the user light headed, dizzy, and left feeling a little high. It can also cause vomiting, headaches, stomach pain, loss of coordination, irritated airways, slurred speech, mental impairment, and even produces patches of scaly skin. Long term use can cause liver and kidney failure, seizures, and can put the user in a coma.There have been reports of users resorting to some pretty desperate measures when naphthalene becomes unavailable. It takes around 6 months of no usage for a user to totally detox from naphthalene abuse.
Why mothballs turn small?
Mothballs are often made from naphthalene. Naphthalene sublimes, that is it goes straight from solid to gas.
Is sulphur a solid?
Yes sulphur is a solid found near volcanoes. It is also yellow.
Why naphthalene undergoes sublimation but has melting point?
Similar to dry ice (solid CO2), pressure is necessary for the formation of liquid naphthalene.
What is the common property of iodine and naphthalene?
they both sublime, in which the solid particles will change directly into gas.
What are four things that can sublime?
Iodine, dry ice (solid carbon dioxide), naphthalene (mothballs), and camphor are examples of substances that can sublime. Sublimation is the process by which a substance transitions directly from a solid to a gas without passing through the liquid phase.
Can sulfur sublime?
Yes, it is possible at temperatures between 25 0C and 50 0C. Besides substances such as naphthalene, ammonium chloride, iodine, dry ice, camphor and anthracene, sulphur also sublimes.
Do naphthalene balls sublime?
Yes, naphthalene balls have the property of sublimation. This means that they transition directly from a solid state to a gaseous state without passing through a liquid state. When exposed to air, naphthalene balls slowly vaporize and release a strong odor.
What is sublimation and examples of substances that can sublime?
Solid carbon dioxide, or dry ice, and Naphthalene both readily sublime at standard atmospheric pressure.
Why does paradichlorobenzene dissolve in naphthalene?
Paradichlorobenzene dissolves in naphthalene because naphthalene is a solid and the other is a liquid. The solid dissolves the liquid.
How naphthalene balls sublimate?
Because it sublimes (changes directly from a solid to a vapor) at room temperature. naphthalene balls are vaporisable substance so they easily turn into vapor , they can turn into vapor because the intermolecular force is very weak so it easily vaporises to gas
To separate mixture of naphthalene and ammonium chloride by sublimation?
no because both sublime on heating
What happens to the solid particles of naphthalene when heated?
Napthalene balls form a gaseous state from solid state without turning into liquod i.e. SUBLIMATION
Appearance of naphthalene?
At standard temperature and pressure, naphthalene is a white crystalline solid.
What process takes place when mothballs get smaller is it evaporation?
The answer to your question is sublimation. I found this answer in my Chemistry book. It states:"Mothballs, which contain the compounds naphthalene or p-dichlorobenzene also sublime, as do solid air fresheners."
