If a liquid sample of naphthalene is heated and remains at 218C until it is completely vaporized you know that 218C is the of naphthalene.?
The temperature of 218°C at which the liquid sample of naphthalene remains constant during vaporization indicates its boiling point. At this temperature, the vapor pressure of naphthalene equals the atmospheric pressure, allowing it to transition from a liquid to a gas. Therefore, 218°C is the boiling point of naphthalene under the given conditions.
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 naphthalene undergoes sublimation but has melting point?
Naphthalene undergoes sublimation because it has weak intermolecular forces that allow it to transition directly from solid to gas phase without melting first. However, naphthalene can still have a melting point due to the presence of a crystal lattice structure that requires enough energy to break to form a liquid.
Can amixture of naphthalene and salt be separated by sublimation?
Yes, a mixture of naphthalene and salt can be separated by sublimation because naphthalene is a solid that sublimates at room temperature, while salt does not. When the mixture is heated gently, naphthalene will transition from a solid to a gas without becoming liquid, leaving the salt behind. The gas can then be cooled to re-condense naphthalene back into a solid form, effectively separating the two components.
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.

Why does paradichlorobenzene dissolve in naphthalene?
Paradichlorobenzene dissolves in naphthalene because they are both nonpolar compounds. Nonpolar substances are soluble in nonpolar solvents like naphthalene due to similar attractive forces between molecules, known as London dispersion forces. This allows paradichlorobenzene to mix and dissolve evenly in naphthalene.
What is the balanced equation for naphthalene dissolving in ethanol?
naphathalene(solid)->naphathalene(liquid)
What does a Graph of melting point and freezing point of naphthalene look like?
The graph of the melting point and freezing point of naphthalene would show a plateau at the melting point, as the solid naphthalene transitions into the liquid phase, and a plateau at the freezing point, as the liquid naphthalene transitions back into the solid phase. The melting point and freezing point of naphthalene are the same at approximately 80 degrees Celsius.
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.

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.
What happens to the temperature of naphthalene during melting?
Lab: Melting / Freezing Point of NaphthaleneObjective: In this lab, you will investigate the melting and freezing point of the substance, naphthalene (moth ball flakes). You will heat solid naphthalene and record temperature changes and examine the graph to determine the melting point of the substance. You will then cool naphthalene and record temperature changes in order to determine the Freezing point of the substance Part A: What happens to temperature as naphthalene melts?Objective: As heat is applied to liquid naphthalene, the temperature rises. As the temperature rises, the naphthalene will eventually start to melt. This lab experiment tries to answer the question: what happens to the temperature of naphthalene as it melts? In this lab, you will heat the liquid naphthalene, and record the temperature changes. You will graph the temperature changes before drawing any conclusions.Part B: Determining the freezing point of naphthaleneObjective: Freezing point is a characteristic property of matter. As heat is taken away from a liquid, the temperature of that liquid decreases as the substance begins to freeze. This lab experiment tries to answer the question: what is the freezing point of an unknown liquid (naphthalene)? In this lab, you will cool liquid naphthalene, and record the temperature changes. You will graph the temperature changes before drawing any conclusions.
How do naphthalene balls become smaller. name the process?
Naphthalene balls decrease in size due to sublimation, a process where the solid naphthalene directly transitions into a gas without passing through the liquid phase. This gradual transition causes the naphthalene balls to shrink over time.
Why naphthalene undergoes sublimation but has melting point?
Naphthalene undergoes sublimation because it has weak intermolecular forces that allow it to transition directly from solid to gas phase without melting first. However, naphthalene can still have a melting point due to the presence of a crystal lattice structure that requires enough energy to break to form a liquid.
Can you make a ball from naphthalene?
Yes by pressing
