Mothballs are usually a solid substance called dichlorobenzene, which sublimates directly into a gas. It has no liquid state. So, it doesn't make a mess, which makes it desirable to have around clothes. However, the gas it produces, while being fatal to moths, is not that good for humans either; it's a neurotoxin. So don't hang out in your closet for too long.

Why do mothballs disappear EXPLAIN?
Mothballs contain a substance called naphthalene or paradichlorobenzene, which slowly evaporates when exposed to air. This process is known as sublimation, where a solid transforms directly into a gas without passing through the liquid phase. As the mothballs evaporate, they gradually disappear, leaving behind no residue or physical remnants.
Why do mothballs disappear slowly EXPLAIN?
its a type of evaporation when the air would slowly evaporate and takes the cotton whith it slowly disapearing
Why do the mothballs in a clothes closet gradually disappear over time?
That is how they work: the insecticidal balls are made of para-dichlorobenzene (PDB, C6H4Cl2), an aromatic which will turn to vapor (sublime) at room temperature. The chemical is also used in urinal deodorizing cakes. Previously, mothballs had been made from the related chemical naphthalene, which has been identified as likely to be carcinogenic in humans.
What do mothballs kill?
Mothballs are typically used to repel and deter moths and other insects, rather than actively kill them. The chemicals in mothballs, such as naphthalene or paradichlorobenzene, release fumes that are toxic to insects and can interfere with their respiration and nervous system, leading them to avoid the area where the mothballs are placed.
Is there liquid mothballs?
Yes, liquid mothballs do exist. They are typically sold as a moth repellent solution that can be sprayed or applied directly to fabrics and other surfaces to deter moths and other insects. Liquid mothballs may contain similar active ingredients as solid mothballs but in a different formulation.
Why do mothballs disappear at room temperature?
Mothballs contain chemicals that slowly turn from a solid into a gas at room temperature, a process called sublimation. As the chemicals vaporize, the mothballs shrink in size and eventually disappear as the gas dissipates into the air.
Mothballs disappear over time is it a chemical change?
No, mothballs disappearing over time is a physical change, not a chemical change. The mothballs are still the same substance, just dispersed or evaporated into the air.
Why do mothballs disappear EXPLAIN?
Mothballs contain a substance called naphthalene or paradichlorobenzene, which slowly evaporates when exposed to air. This process is known as sublimation, where a solid transforms directly into a gas without passing through the liquid phase. As the mothballs evaporate, they gradually disappear, leaving behind no residue or physical remnants.
What happen when the mothballs exposed under the sun?
Exposure to sunlight may cause mothballs to release their chemicals more quickly, resulting in faster evaporation. This can result in a stronger odor and potentially more rapid depletion of the mothballs. It is best to store mothballs in a cool, dark place to prolong their effectiveness.
Why do mothballs disappear slowly EXPLAIN?

Who said 'How quickly all things disappear'?
Marcus Aurelius - How quickly all things disappear, in the universe the bodies themselves, but in time the remembrance of them
How can a fish disappear from a tank?
A fish can disappear from a tank if it jumps out, is eaten by another fish, or if it dies and decomposes quickly.
Are mothballs legally sold?
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.
Is mothballs disappear over time a chemical change?
It is a Physical Change.
How many hours do a mothballs melt?
Bleh. Mothballs are gross.
What is the scientific name for mothballs?
The scientific name for mothballs is naphthalene.
Will the heat speed up moth ball disintegration?
Excessive heat may speed up the sublimation process of mothballs, causing them to vaporize more quickly. However, the complete disintegration of mothballs depends on several factors, such as temperature, air circulation, and material composition.
