It means that the freezing or melting points do not change, that they are always the same, depending on the type of matter. For eg. the melting point or freezing point of water is 0○ Celsius and the boiling point is always 100○C.

What is freezing point elevation?
This is not a common phenomenon. Usually it is boiling points that are elevated, and freezing points are depressed. It is possible that a freezing point could be raised (elevated) due to the presence of an impurity with a much higher freezing point.Changes in boiling and freezing points are typically due to impurities in compound.See the Related Questions to the left for more information about freezing point depression and boiling point elevation problems.
What are the six phases of matter and their meaning?
freezing -to pass from the liquid to solid state by loss of heat
What happens to the boiling point of a solution as the concentraion increases?
Boiling-point elevation describes the phenomenon that the boiling point of a liquid (a solvent) will be higher when another compound is added, meaning that a solution has a higher boiling point than a pure solvent. This happens whenever a non-volatile solute, such as a salt, is added to a pure solvent, such as water. The boiling point can be measured accurately using an ebullioscope.
What is the meaning of super heat?
Superheated steam is steam at a temperature higher than water's boiling point
How can separate 2 mixed liquids from each other?
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).
Compare the boiling and freezing points of 1m solution of glucose to a 1m solution of Cacl2. Why does CaCl2 have a higher boiling and a lower freezing Please explain not just say its 1m and then 3m?
Boiling and freezing points are colligative properties, meaning they depend on the number of solute particles dissolve in solution. Glucose is a molecular compound so it is one particle dissolved in solution. CaCl2 will dissociate into three particles in solution. There are three times as many particles present in solution when CaCl2 dissolves.

What is the meaning of rolling boiling in cooking?
It refers to a boil. When water is boiling, a rolling boil is when you are stirring the water and it is still boiling.
What is the equation for isothermal process?
At the boiling point the energy goes into breaking the intermolecular bonds, but the average kinetic energy stays constant and so does the temperature until all of the bonds are broken and the substance is in the vapor state.
What is the meaning of freezing?
of Freeze, Tending to freeze; for freezing; hence, cold or distant in manner.
What is the meaning when something is boiling or melting?
When something is melting its evaporation. When something is boiling its condensation.
Does the gas constant R vary with temperature?
No, the gas constant, or any constant, is constant meaning it doesn't change.
What is the opposite meaning to constant?
changing.
Where does coolant go?
It prevents the liquid within the engine from freezing or boiling. Coolant does just what the name implies. It keeps the engine cool, meaning it keeps the engine at the correct operating temperature. It also prevents corrosion within the engine and cooling system.
What is the meaning of h in the planck's constant?
The meaning of h in the Planck's constant is the photon having a frequency of one unit in any scale.
What is the meaning of poaching?
of Poach
What is the physical meaning of time constant?
Physically, the constant represents the time it takes the system'sstep responseto reachof its final (asymptotic) value.
