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 another name for the freezing point of a material?
Another name for freezing point is melting pointsince the temperature at which a substance freezes is also the temperature at which it melts, going in the other direction.Freezing point could also be referred to as congelation point.
If the freezing point of a particular substance is 52 degrees celsius then what would its melting point be?
The freezing point and melting point of a substance are the same, so the melting point would also be 52 degrees celsius.
Freezing point of pure substance 21 degrees what is the melting point?
The melting point of a substance is the same as its freezing point in a closed system. Therefore, if the freezing point of a pure substance is 21 degrees Celsius, its melting point would also be 21 degrees Celsius.
What is the melting and freezing point of iodine?
The melting point of iodine is 113.7 degrees Celsius, and the freezing point is the same as the melting point, which is 113.7 degrees Celsius.
What is the Hypothesis of the melting and freezing point of naphthalene?
The hypothesis for the melting and freezing point of naphthalene could be that the melting point of naphthalene will be higher than its freezing point due to the typical behavior of most substances where solids melt at higher temperatures than they freeze. The hypothesis may also include factors like the purity of the naphthalene sample affecting its melting and freezing points.
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.
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 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.
What is the freezing of adding p-nitromethylbenzene to the freezing point of naphthalene?
When p-nitromethylbenzene is added to naphthalene, it can lower the freezing point of the solution due to colligative properties, specifically freezing point depression. The presence of p-nitromethylbenzene disrupts the orderly arrangement of naphthalene molecules as they freeze, requiring a lower temperature to achieve solidification. The extent of this freezing point depression depends on the concentration of p-nitromethylbenzene in the solution.
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 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.
What is its melting point when the freezing point of a substance is 68C?
The freezing point is 680C
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
