Naphthalene has high or low melting point?
Naphthalene has a relatively low melting point of around 80 degrees Celsius.
What is the freezing point depression constant for naphthalene?
The freezing point depression constant for Naphthalene is 6.9 degrees Celsius/mhttp://en.wikipedia.org/wiki/Freezing-point_depression
What is its melting point when the freezing point of a substance is 68C?
The freezing point is 680C
What kind of property is melting point and freezing point of water?
The melting point and freezing point of water are physical properties. The melting point is the temperature at which ice (solid) changes to water (liquid), while the freezing point is the temperature at which water (liquid) changes to ice (solid).
How is the freezing point of a substance related to the melting point of the substance?
The freezing point and melting point of a substance are the same temperature but represent opposite phase transitions. The freezing point is the temperature at which a liquid turns into a solid, while the melting point is the temperature at which a solid turns into a 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.
Naphthalene has high or low melting point?
Naphthalene has a relatively low melting point of around 80 degrees Celsius.

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.
What is the difference melting point of sodium iodide and naphthalene?
NaI has ions and has strong electrostatic force of attraction, hence high melting point. Naphthalene has weak van der Waals forces of attraction between the molecules and hence have low melting point.
What is the effect of adding p nitrotoluene to the freezing point of naphthalene?
Adding p-nitrotoluene to naphthalene will lower the freezing point of the mixture. This is due to the phenomenon of freezing point depression, where the presence of a solute lowers the freezing point of the solvent. The greater the concentration of the solute in the solvent, the lower the freezing point will be.
Why does the freezing point decrease when naphthalene is added in camphor?
When naphthalene is added to camphor, it disrupts the crystalline structure of camphor by interfering with the intermolecular forces between camphor molecules. This disruption causes the camphor molecules to have a harder time coming together in an organized manner for freezing, resulting in a decrease in the freezing point.
What is its melting point when the freezing point of a substance is 68C?
The freezing point is 680C
What will melt faster pure or impure naphthalene?
Impure naphthalene will typically melt faster than pure naphthalene. The impurities present in impure naphthalene lower its melting point, making it easier for the solid to convert into a liquid state at a lower temperature.
Are the melting point of solid and freezing point of liquid of a substance different?
yes the melting point of solid and freezing point of liquid of a substance is differ but in the case of water the melting and freezing point is same.
What is the melting freezing point of water in Kelvin?
Freezing point: 273.15 K Melting point: 373 K
Are these chimichel changes melting malting point freezing?
No. Melting and freezing are physical changes. Melting point is a physical property.
