What happens to naphthalene ball when heated?
When naphthalene balls are heated, they undergo a process called sublimation, where they transition directly from a solid to a gaseous state without becoming a liquid. This releases vapors that are toxic to insects like moths, which is why they are commonly used as insect repellents in closets and storage areas.
How will you separate naphthalene from mixture of naphthalene and sodium chloride?
Naphthalene can be separated from sodium chloride by sublimation. When the mixture is heated, naphthalene will sublimate, turning from a solid to a gas, and can be collected separately from the solid sodium chloride.
What happens to the solid particles of naphthalene when heated?
When naphthalene is heated, the solid particles sublimate, meaning they change directly from a solid to a gas without passing through a liquid phase. This sublimation process causes the naphthalene to vaporize and release a characteristic odor.
If a liquid sample of naphthalene is heated and remains at 218 and degC until it is completely vaporized you know that 218 and degC is the of naphthalene.?
Boiling point.
Why is solid naphthalene not heated directly with a Bunsen burner?
Solid naphthalene is not heated directly with a Bunsen burner because it can undergo sublimation, meaning it can turn directly from a solid to a gas without passing through the liquid phase. This process can lead to the rapid vaporization and combustion of naphthalene, increasing the risk of fire or explosion.
What is the black particle of an naphthalene when it gets heated?
soot

What is the effect of heat on the naphthalene ball?
Napthlene balls sublimates (turns into vapour) when heated...
If a liquid sample of naphthalene is heated and remains at 218 until it is completely vaporized you know that 218 is the of naphtanlene?
If a liquid sample of naphthalene is heated and remains at 218°C until it is completely vaporized, you know that 218°C is the boiling point of naphthalene. This temperature indicates the point at which the liquid naphthalene transitions to its gaseous state under atmospheric pressure. The boiling point is a characteristic property of a substance and helps identify it.
Why is solid naphthalene not heated directly with a Bunsen burner?
Solid naphthalene is not heated directly with a Bunsen burner because it can undergo sublimation, meaning it can turn directly from a solid to a gas without passing through the liquid phase. This process can lead to the rapid vaporization and combustion of naphthalene, increasing the risk of fire or explosion.
What happens to sulphur when it is added to naphthalene?
When sulfur is added to naphthalene, it can form a chemical compound known as sulfurized naphthalene. This can improve the lubricity and anti-wear properties of the naphthalene, making it suitable for use as a lubricant or as an additive in lubricating oils.
Which physical method can be used to separate naphthalene from sand?
Sublimation can be used to separate naphthalene from sand. Naphthalene can be heated to change it directly from a solid to a gas, leaving the sand behind. The gas can then be collected and cooled to form solid naphthalene again.
What happens to naphthalene when it sublimes?
When naphthalene sublimes, it transitions directly from a solid to a gas phase without passing through a liquid phase. This process occurs when the substance is heated and the vapor pressure exceeds the atmospheric pressure. As the naphthalene molecules gain enough energy to break free from the solid phase, they transform into a gas.
Does naphthalene decompose when gently heated?
Yes, naphthalene sublimes and undergoes vaporization at temperatures above 80 degrees Celsius rather than decomposing directly. At temperatures exceeding its sublimation point, naphthalene converts from a solid to a gas without passing through a liquid phase.
