Explanation of why naphthalene balls become smaller in size:
Naphthalene balls are commonly used as a moth repellent. They are kept in storage spaces with woolen clothes to protect them from moth infestation. Over time, the naphthalene balls become smaller in size. This happens because of a process called sublimation.
What is sublimation?
Sublimation is the process of a solid turning directly into a gas without passing through the liquid state. In the case of naphthalene balls, they slowly convert into a gas and evaporate into the air. This process is known as sublimation.
What type of change is involved during the process?
The change that occurs during sublimation is a physical change. This is because the naphthalene balls do not change their chemical composition during the process of sublimation. They only change their physical state from a solid to a gas.
Why do naphthalene balls undergo sublimation?
Naphthalene balls undergo sublimation due to their chemical properties. Naphthalene is a volatile organic compound (VOC) that has a low boiling point and a high vapor pressure. This means that it has a tendency to evaporate easily and quickly. When naphthalene balls are exposed to air, they start to evaporate due to the high vapor pressure of naphthalene. This leads to the process of sublimation.
Conclusion:
In conclusion, naphthalene balls become smaller in size due to the process of sublimation. This is a physical change that occurs because of the chemical properties of naphthalene. Naphthalene is a volatile organic compound that evaporates easily and quickly, leading to the process of sublimation.

Napthalene is a sublime substance I.e goes to gaseous state directly from solid without converting to liquid the process is continuous and the vapors are not visible hence the balls appear smaller by day.
