How do naphthalene balls disappear with time?

Naphthalene undergoes sublimation easily, i.e., the change of state of naphthalene from solid to gas without the intervention of the liquid state. Thus, naphthalene balls keep forming naphthalene vapours that disappear into the air with time without leaving any solid.

How do mothballs disappear?

Mothballs slowly disappear as they turn into gas and mix with the surrounding air. Mothball fumes can stick to fabrics or clothing following storage, requiring items to be aired out and washed to remove the odor.

Do naphthalene balls evaporate?

Both of these formulations have the strong, pungent, sickly-sweet odor often associated with mothballs. Both naphthalene and 1,4-dichlorobenzene undergo sublimation, meaning that they evaporate from a solid state directly into a gas; this gas is toxic to moths and moth larvae.

Why do naphthalene balls disappear in clothes?

Naphthalene or mothballs kept between clothes disappear over a period of time because naphthalene balls undergo sublimation and form naphthalene vapours, which disappear into the air.

Why naphthalene balls disappear with time without leaving any?

Naphthalene undergoes sublimation easily i.e., the change of state of naphthalene from solid to gas without the intervention of the liquid state. Thus, naphthalene balls keep on forming naphthalene vapours which disappear into the air with time without leaving any solid.

Why naphthalene balls kept in clothes at home disappear after some time name two other such substances?

Naphthalene is a substance that is sublime in nature; this basically means it has a tendency to change its state from solid directly to the gaseous form without paying through the intermediate liquid state. However, a while after storage, these balls disappear on their own owing to the phenomenon of sublimation.

What happens when moth balls get wet?

Wet mothballs are even more potent than dry ones. And the wetness can be profound, like exposure to water from a flood or leaky pipe, or mild, in the form of high humidity. Either will cause the odor to be more potent and sublimation to be more rapid.

How long does naphthalene take to evaporate?

a single naphthalene mothball in open air may dissipate in a 3-6 months. a single naphthalene mothball placed under clothing and not in open air may dissipate in 12 months.

Why naphthalene balls disappear with time without leaving any solid?

Ans. (a) Naphthalene balls disappear with time without leaving any solid, because naphthalene balls sublime and directly changes into vapour state without leaving any solid.

Why are naphthalene balls kept in public toilet?

Naphthalene balls are used to kill moth, cockroaches and insects found in toilets.

Does naphthalene absorb moisture?

Naphthalene balls can be used in cupboards to help absorb some moisture and keep the clothes fresh. You can also use some neem leaves to avoid dampness and banish the musty smell.

Why do naphthalene balls disappear after some time?

Naphthalene balls disappear because of the process of Sublimation at room temperature (a process by with solid directly changes to gas without going through the intermediate state of matter, liquid is called as Sublimation). So as it goes through Sublimation, the naphthalene balls is converted to gas from solid.

What is the sublimation of naphthalene?

Naphthalene undergoes sublimation easily, i.e., the change of state of naphthalene from solid to gas without the intervention of the liquid state. Thus, naphthalene balls keep forming naphthalene vapours that disappear into the air with time without leaving any solid.

How does naphthalene change from solid to gas?

Naphthalene undergoes sublimation, the change from a solid directly into a gas without going through the liquid phase, that is why it gets disappeared into air. Compounds with relatively high vapor pressures have low intermolecular forces and undergo sublimation.

Is it dangerous to sniff naphthalene balls?

Yes, sniffing naphthalene balls can be hazardous to health. Also, many people keep these balls in kitchen drawers where food items are kept. It is fine as long as the items are packed inside a container, but it can be dangerous if the items are kept unpacked as the ball vaporizes and mixes with contents like flour, etc.
