Mothballs get smaller over time primarily due to the sublimation of their active chemical compounds, such as naphthalene or paradichlorobenzene. These substances transition from a solid state directly into gas without becoming liquid, causing the mothballs to gradually shrink. Additionally, exposure to air and humidity can accelerate this process. As the mothballs evaporate, their effectiveness as a pest repellent diminishes.
Bleh. Mothballs are gross.

Smaller.
it make it smaller and a little lager not a lot
In value, a penny is smaller. In size, a dime is smaller.
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."
Mothballs are legally sold for use of the purposes listed on the label. It is illegal to use mothballs for other purposes including using mothballs in gardens.
Bleh. Mothballs are gross.
The scientific name for mothballs is naphthalene.
As I opened the wardrobe, mothballs fell out.
the mothballs will fly away
I have never known mothballs to cause nose bleeds.
While it is not proven that mothballs will keep wasps away, there is evidence that they do. Mothballs also seem to keep small rodents away too.
NO! Not safe!
Yes, mothballs contain naphthalene, which is a poison if inhaled.
The gradual vaporization of mothballs in a closet is a physical change. This is because the mothballs are changing from a solid state (solid mothballs) to a gaseous state (mothball vapor) without undergoing a chemical reaction.
No, most modern mothballs contain 1,4-dichlorobenzene, while older mothballs contained naphthalene. Neither of these chemicals are useful in the production of methamphetamine.
