Note: While naphthalene is a solid at room temperature, its strong odor suggests it has a significant vapor pressure. This explains its use in mothballs, as it readily sublimes into the air and repels insects.
This list covers some of the key physical properties of naphthalene. Further research can provide more detailed information about its behavior under different conditions.
