The boiling and melting points are very different.


No, all liquids have different melting and freezing points. The boiling point of water is 100°C or 212° F,freezing point 0 degrees C. other liquids have a higher boiling point for example the boiling point of Ethanol is 78.37° C and the frezing point is 114.6 degrees C some liquids may have the same boiling or freezing points then other but most have different ones.


Boiling and melting points are very different.



Melting points can be helpful in distinguishing different substances. Pure substances usually have a unique fixed melting point. Same goes for the boiling points.


Liquids and soilds can turn into one another based on their melting points.


No the temperature at which liquids boil varies with the liquid and with the ambient pressure.


Boiling point is just one property. There are many other properties that could vary between the two liquids.


The freezing temperature of water is 32 degrees Fahrenheit and boiling point of water is 212 degrees Fahrenheit. So freezing points and boiling points are not the same.


Fractional Distillation is the best because no two liquids can have the same boiling points.


yes, for the same molecule. However, some substances don't have a liquid phase and so the melting point is exactly the same as the boiling point at normal pressures (sublimation is the phase change from solid -> gas)


I am guessing by fractional distilation because they should have diffrent boiling point but if the boiling points are the same then add salt to make them impurities and have diff boiling points then do fractional distillation


At the same atmospheric pressure, yes. That's kind of the definition of boiling point: when the vapor pressure is the same as the atmospheric pressure.


The melting point is the same as the freezing point; however, the boiling point is not the same as the melting point.


A property is something that describes matter. Since every substance does not have the same boiling point or melting point these can be used to help describe the substance.


yes, i belive it does. however, the amount of water will change the amount of time it takes for either of them to occur. most water is not 100% pure, so boiling points can sometimes vary by a fraction. So the answer is melting and boiling points


Yes the melting and freezing points are the same.


Because they are unique to each pure substance. Different substances usually have different melting points, so determining the melting point of a substance can narrow down the possibilities for the identity of the substance. Likewise different substances usually differ in their boiling points, so boiling point can narrow down the possible identities of a substance. Although two substances can have nearly identical melting points or have nearly identical boiling points, it is extremely rare for two different pure substances to have BOTH the same melting point AND the same boiling point, so taking the two together is usually enough to uniquely identify a substance, or at the very least narrow it down to a very small list.


No boiling is heating and energy is added and melting the solid turns into a liquid.


liquids with the same boiling points. because they would evaporate at the same time leaving you without a solution.


You could test the resulting liquid by determining its boiling point and melting point. If they are the same as the boiling and melting points for water, then it is probably water and a physical change rather than a chemical change has occurred.


In most cases, two mixed liquids can best be separated by the process of distillation, in which the liquid with the lower boiling point is boiled off and collected as vapor, and it can then condense back into a liquid. It is also possible to separate two mixed liquids by cooling them to the point that one of the liquids freezes; no two liquids would have exactly the same freezing point, just as they do not have exactly the same boiling point (of course, if the freezing points or the boiling points are very close, that makes the separation process harder).

Also, surprisingly, if you mix two substances with the same melting point, the mixture will NOT melt at the expected temperature, so when you have a shortlist based on melting point you take your unknown and mix it with one of the suspects. If it melts at the right temperature, you have identified it. If not, you try the next one.


The melting and boiling points of a substance (in this case I am assuming you are referring to a pure substance, and not a mixture), are the same. The triple point is defined by the temperature and pressure at which solid, liquid, and vapor of a substance, can coexist in equilibrium. At any pressure below the triple point, only sublimation and condensation are possible (no liquid phase is possible). Between the triple point pressure and the critical point pressure, there is a difference between the melting and boiling points, of a substance. The melting point temperature will be lower than the boiling point. At the critical point, the densities of the liquid and vapor phases, have merged, and boiling no longer occurs. At and above the critical point, you cease to get liquid and vapor, but you get what is referred to as a "supercritical fluid".


cause all pure substances have a fixed boiling and melting point unless impurities is added their boiling and melting will always remain the same.
