Why naphthalene undergoes sublimation but has melting point?
Similar to dry ice (solid CO2), pressure is necessary for the formation of liquid naphthalene.
Do naphthalene balls sublime?
Yes, naphthalene balls have the property of sublimation. This means that they transition directly from a solid state to a gaseous state without passing through a liquid state. When exposed to air, naphthalene balls slowly vaporize and release a strong odor.
Does liquid naphthalene conduct electricity?
Naphthalene is a Ionic Substance. Hence, Ionic substance do not conduct when solid. But they do conduct when melted or dissolved in water - and they decompose at the same time. Therefor molten Naphthalene conduts electricity as the ions become free to move when dissolved in water.
What are 2 solid substances that don't go through a liquid state when heated and go straight to gas?
Naphthalene and camphor the process is sublimation
What has the change is a state of matter from a liquid to a gas?
sublimation is the process in which a solid directly gets converted into a gas. example:camphor, naphthalene
Why does paradichlorobenzene dissolve in naphthalene?
Paradichlorobenzene dissolves in naphthalene because naphthalene is a solid and the other is a liquid. The solid dissolves the liquid.
Why naphthalene undergoes sublimation but has melting point?
Similar to dry ice (solid CO2), pressure is necessary for the formation of liquid naphthalene.
During the cooling of naphthalene explain why the naphthalene must be stirred continuosly?
to ensure that the temperature is uniform throughout the liquid
What is the balanced equation for naphthalene dissolving in ethanol?
naphathalene(solid)->naphathalene(liquid)
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.
Can you make a ball from naphthalene?
Yes by pressing

Is naphthalene a base?
No naphthalene is an organic aromatic hydrocarbon.
How will you separate naphthalene from mixture of naphthalene and sodium chloride?
werde

Can iodine and naphthalene be separated by sublimation?
naphthalene and iodine can be separated by sublimation
