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 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.
Why mothballs disappear quickly?
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.
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.
Without Israel and America will civilization slowly disappear?
Not likely. Modern civilization first arose and developed greatly in Europe. Without Europe civilization would most likely slowly disappear.
What happens when mothballs are added to baking soda and vinegar?
This demonstration actually works better when the mothballs are added to a clear soda drink (e.g. 7-Up). The mothballs by themselves are just a little bit denser than the liquid, so they sink to the bottom. As carbon dioxide bubbles accumulate on the outside of the mothballs they eventually become buoyant and slowly rise to the top. While at the top the bubbles break and the mothballs sink again. This will repeat until the liquid runs out of carbon dioxide. As the mothballs are not soluble in water, if you use a clear soda drink you can still drink it when you are done (after removing the mothballs so you won't risk swallowing one and choking), but it of course will be somewhat "flat".
Why does the automobile coolant in your reservoir disappear?
It does disappear slowly due to evaporation. But if it is going fats, I would look for a leak. I meant "going FAST"!
What does maheoe mean in the Hawaiian language?
