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.
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.
Why mothballs turn small?
Mothballs turn small because they are made of a volatile chemical compound, such as naphthalene or paradichlorobenzene, that sublimes into a gas at room temperature. As the compound sublimes, it changes from a solid state directly to a gas, causing the mothballs to shrink over time.
How fast does mothball sublime?
depends on temperature. Very slowly at room temperature.
What temperature does mothballs boil?
Mothballs are usually made of naphthalene. Naphthalene has a boiling point of aroun 218oC (424oF).
Why are mothballs so effective in driving away pests?
It is because mothballs have a very high melting temperature & they stench a lot.
Why do mothball disappear after a few weeks?
Mothballs contain a volatile chemical, typically naphthalene or paradichlorobenzene, which sublimates, turning from solid to gas. Over time, the concentration of these chemicals decreases as they evaporate into the air, leading to the mothballs disappearing. Additionally, environmental factors like temperature and airflow can accelerate this process. As the chemicals dissipate, their effectiveness in repelling pests diminishes.
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
What property of compound to be used in mothballs for clothes protection?
The compound used in mothballs for clothes protection needs to be volatile, meaning it can easily turn into a gas at room temperature to effectively repel moths. Naphthalene and paradichlorobenzene are common compounds used in mothballs due to their ability to release a strong odor that repels moths. Additionally, these compounds need to be toxic to insects but not harmful to humans in the recommended amounts.
Will a magnet repel if frozen?
A frozen magnet will act the same way it does at room temperature. Freezing doesn't make its magnetic properties disappear.
How long for mothballs to disintegrate under the mobile home?
Mothballs can take several weeks to several months to completely disintegrate depending on the conditions such as temperature, humidity, and airflow. It is important to consider the potential health hazards of the chemicals in mothballs and to follow recommended safety guidelines for their use and disposal.
