What property of napththalene balls allows it to be used in moth balls for cloth protection?

Naphthalene balls, or moth balls, contain naphthalene which is a strong insecticide and repellent that helps deter moths and other insects from damaging clothes. The strong odor of naphthalene is effective in keeping pests away from stored garments.


How to make moth balls last longer?

To make mothballs last longer, store them in airtight containers when not in use to prevent them from dissipating quickly. Place them in areas with low humidity and good ventilation to help extend their effectiveness. Additionally, replacing old mothballs with fresh ones periodically can help in maintaining their potency.


Explain why naphthalene or moth balls disappear without wetting the clothes?

Naphthalene (moth balls) sublimes, which means it transitions from a solid to a gas without going through a liquid phase. This process occurs due to the substance's high vapor pressure at room temperature, causing it to evaporate directly into the air. As a result, naphthalene can disappear from clothes without leaving any visible residue.


What are the four substances that sublime?

Carbon dioxide (CO2), iodine (I2), "moth balls," which are mostly naphthalene (C10H8), and arsenic (As) at really high temperatures.


Which phase transition occurs when moth balls slowly become smaller and eventually disappear?

The moth balls get smaller by the process of evaporation. Due to the health risks of 1,4-dichlorobenzene (newer type), and flammability of naphthalene (older type), other substances like camphor are sometimes used.
