what does a graph of melting point an freezing point of naphthalene look like
The freezing point is the same as the melting point, temperature-wise.
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.
The freezing point of salt is also its freezing point. This is the case with any substance, as it is the temperature that an element changes from the solid to liquid phase or the liquid to solid phase.
Cerium's freezing point or the melting point is 795 oC.
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.
The higher the temperature, the more the naphthalene to be melt.
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.
low melting point
When adding a solute to a solvent, the freezing point decreases and is also known as freezing-point depression. Hence when naphthalene is added to camphor the freezing point decreases.
The freezing point depression constant for Naphthalene is 6.9 degrees Celsius/mhttp://en.wikipedia.org/wiki/Freezing-point_depression
The melting point of lauric acid is 43,8 oC.
It is easily checked by melting point of Naphthalene, if it is pure its melting point is 79 Celsius otherwise less than 79 Celsius.
The melting point (or freezing point) of oxygen is -218,79 0C.
It decrease the freezing point due to the temperature as observed....
When determining the melting point or the freezing point of something....that is when they are used....
The freezing point is the same as the melting point, temperature-wise.
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.
