Why a sharp melting point could not be obtained always?
the melting point of pure substances is always being sharp. it means that the boiling point it have it will boil at that point not some up or down but on same temperature in other words we say that it has no impurities because of impurities it boiling point varies and it has many other components and boiling point of every component is different so that why the boiling point of impure compounds varies or it don t have exact value and the pure compounds have same elements combine together and every molecule boil at particular point so it has sharp melting point or exact point
Is a sharp melting point for a crystalline organic substance always indicates a pure single compound?
In general, a sharp melting point for a crystalline organic substance can suggest a pure single compound. However, impurities or different polymorphs can also affect the sharpness of the melting point. Additional analysis, such as TLC or NMR, may be needed to confirm the purity of the compound.
What is the term of melting point range?
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.
Which one of the following tin-lead solders has the lowest melting point?
70/30 (70% tin, 30% lead) the more lead in an alloy the higher the melting point is.
How does the melting point of the crude sample compare with that of the purified sample?
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
Why urea has sharp melting point but glass does not?
Urea has a sharp melting point because it undergoes a crystalline-to-liquid phase transition at a specific temperature. In contrast, glass does not have a sharp melting point because it is an amorphous solid with a disordered atomic structure, resulting in a gradual softening and melting process over a range of temperatures.

What is the difference between the melting point and slip point?
Melting point s can be "sharp" where the phase change occurs at a particular temperature, or the solid may soften and then melt over a range of temperatures. Conventionally melting point refers to the sharp melting point, and this is exhibited by pure chemical compounds that do not decompose. Slip melting point usually refers to a technique for measuring the point at which a waxy solid "slips" in a tube -waxy solids such as hydrocarbons produced from petroleum oil are mixture and melt over a range and this is near reproducible way of obtaining a diagnostic single "melt" temperature for the mixture.

Does fiber have a high melting point?
Fiber typically has a lower melting point compared to metals and other high-temperature materials. The melting point of fiber can vary depending on the type of material it is made from, such as glass, carbon, or polymer fibers. Generally, synthetic polymer fibers have lower melting points than natural fibers like wool or silk.
What simple test can you do to determine if a given solid is pure or not?
One simple test to determine if a solid is pure is to measure its melting point. A pure substance will have a sharp melting point, while impurities will cause the melting point to be lower and more spread out. Comparing the measured melting point to the known melting point of the pure substance can help determine its purity.
How does the melting point of the crude sample compare with that of the purified sample?
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
What do you call the temperature at which a solid changes to a liquid?
This is the melting point.
What is the difference between a crystaline mineral and an amorphous mineral?
because amorphous solids are that solids that don't have geometrical shape and don't have particular melting point but crystalline solids have characterstic geometrical shape and have sharp melting point.
You find that a particular solid shatters unpredictably and does not have a sharp melting point You determine that this is?
An amorphous solid, most likely a glass.
