Because they are not pure compounds !

Why amorphous solids do not have sharp melting points while crystalline solids do have?
in crystalline solids, the atoms are arranged in an ordered fashion and hence they have sharp melting points. amorphous solids, due to random arrangement of the atoms do not have sharp melting points.
Why crystalline solids have sharp melting points whereas amorphous do not?
"As the atoms of Crystalline solids have specific shape and same distance,so they have same K.E,intermolecular forces of attraction and geometrical shape due to which Crystalline solids are blessed sharp melting points."
Does fiber have a high melting point?
Fibres have a sharp melting point (a high melting point) due the strong forces with which the chains are closely packed giving them high tensile strength.
How do you measure refractoriness?
since most of the refractories are mixtures of metal oxides they donot have sharp melting points.so the refractoriness of arefractory is generally measured as the softening temperature and is expressed in terms of pyrometric cone equivalent (PCE)
What is the melting point for grass?
Applying heat to grass will not cause it to melt but to burn. Glass is a silica compound that due to the addition of soda softens at about 1500 °C (2700 °F) It is not a true "melting point" since amorphous solids do not have sharp melting points like crystalline solids do.

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
Define amorphous solid?
Generally they are two types of solids 1. Crystalline solids 2. Amorphous solids. Amorphous solids are those solids which having different properties in different directions. They didnt have sharp melting and boiling points.
Is a sharp melting point for a crystalline organic substance always indicates a pure single compound?
Nope; not always. So the answer would be false. You have to realize that there might be impure substances mixed. Likewise impure substance can either lower the melting point or increase it :)M. Bilal :)
Does fiber have a high melting point?
Fibres have a sharp melting point (a high melting point) due the strong forces with which the chains are closely packed giving them high tensile strength.
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 is a pure crystalline compound so has a sharp melting point while glass is an amorphous mixture.

When using culantro do you leave on the sharp points?
no but ou can eat te sharp points
What is the term of melting point range?
The crystalline solids have a sharp melting point say 87oC but most of the amorphous solids do not have a sharp melting point they have a range of melting say they started melting at 87oC and continue till 89oC.
