The interval between the beginning of liquefaction and complete liquefaction
Melting points should always be reported as a range. Maybe during purification process was not perfect, and there were impurities in the caffeine that were affecting the melting point. The melting point is depressed due to impurities in the sample. The caffeine is usually not 100% pure, maybe improper isolation procedure and also the impurity is likely solvent.
it is something that you melt
MELTING POINT:-The point at which solid starts melting and turn into liquid it iscalled MELTING POINT.BOILING POINT:-The point at which liquid molecules starts escaping fromthe surface and turn into gas is called BOILING POINT.
the difference of greatest data value minus least data value = data range
the point where a system ends and surroundings begin
It is predicted that the melting point of livermorium will be in the range 350-500 0C .
By definition, they are the same!
An impure sample will have a lower melting point, and will also have wider melting point range than that of a pure sample of the same substance. a sharp melting point range can also indicate a eutectic mixture
It is incorrect to speak of a "melting point" because melting is a process, not a specific point. Instead, we should refer to the melting range, which indicates the range of temperatures over which a substance changes from a solid to a liquid.
It is a compound. All pure elements have a certain exact melting point.
Even in pure crystals, the melting point range can still exist due to imperfections or defects in the crystal lattice. These defects can cause different parts of the crystal to melt at slightly different temperatures, leading to a range of melting points rather than a single sharp melting point.
not 0 degrees
The melting point range refers to the temperature range over which a substance transitions from a solid to a liquid state. It is the interval in which the solid begins to melt and continues to completely liquefy. This range is typically represented by a lower and upper temperature limit.
strong intermolecular forces attract the molecules
It has a melting range of 182 to 187 degrees Celsius.
Montelukast sodium has a melting point range of approximately 243-253 degrees Celsius.
The melting point range of maleic acid is typically between 130-139°C.
