Heating mothballs can cause them to sublimate, releasing toxic fumes containing chemicals like naphthalene or paradichlorobenzene. Inhaling these fumes can lead to symptoms like headache, dizziness, nausea, and respiratory irritation. It is important to follow safety precautions and use mothballs as directed to prevent exposure to these harmful substances.
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.
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.
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.
Zinc carbonate decomposes when heated to give zinc oxide.
The Dancing Mothballs experiment was invented by physicist Richard Feynman. This experiment involves placing mothballs on a vibrating surface to observe their movement patterns, which can help illustrate concepts of Brownian motion.
the mothballs will fly away
You increase the dose.
When matter is heated it will expand
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.
no answer
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".
Bleh. Mothballs are gross.
The scientific name for mothballs is naphthalene.
When an enzyme is heated it is denatured, which means that it can no longer function.
Ozone when heated gets decomposed. It decomposes into oxygen.

It cooks.
