The compound CO2 sublimes readily at 25 degrees Celsius Which properties are usually associated with a compound that undergoes this kind of change?

Naphthalene, as well as any other solid, may sublimate at any temperature and pressure. The triple point parameters are irrelevant. The pressure of other components that is, air is irrelevant as well. Until it reaches the saturated vapor pressure or until your mothball is all gone, whatever happens sooner , naphthalene will sublimate. The solids which we perceive as incapable of sublimation like steel, glass, or rocks have very low vapor pressure, so their sublimation would take forever.

Other than that, everything above applies to them as well. Then again, some solids melt upon heating and some do not, but that's another story. We aren't talking about any heating, are we? By definition, going from solid to gas directly is sublimation. If moth balls were not solid, but liquid instead, then we'd call the process evaporation.

I got my answer at wikipedia after a little through study, it goes like this - Evaporation that occurs directly from the solid phase below the melting point, as commonly observed with ice at or below freezing or moth crystals napthalene or paradichlorobenzene , is called sublimation. Naphthalene sublimes easily because it has a low triple point.

A substance's triple point is the temperature and pressure at which it can exist in all three phases of matter: solid, liquid and gas. Under ordinary atmospheric pressure, naphthalene's triple point is degrees Fahrenheit.

Naphthalene is the active ingredient in mothballs. Marina Stojanovska. Under a Creative Commons license. In this paper we offer a lecture demonstration showing the existence of all three states of iodine, supported by a short video-clip, hoping to give a contribution to the correction of misbelieves about the process of sublimation and the examples of subliming substances.
