Amorphous solids have no definite melting point because their particles are arranged randomly. Amorphous solids do not have crystal form or definite melting point.
No
Mass and volume
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.
Name this crystalline solid; each compound and material have a different melting point.
These are two out of three categories of solids according to their geometry and arrangement. Crystalline solids have proper geometry having the particle arranged on definite axes possessing sharp melting point such as common salt, diamond, etc. Whereas amorphous solids neither have ordered arrangement nor a definite geometry. They have long range melting point such as glass, plastic, etc.
they must have strong network structures
At its melting point, which depends on what it is.
The crystal lattice will slightly effect the high vacuum and eventually decrease the melting point particularly decomposing solids.
Very hard, very high melting point, poor conductor of electricity and heat, and not soluble in water.
the melting points differ to differant solids
Covalent compounds have a lower melting point.
No
Amorphous solids do not have a definite melting point or regular repeating units. An amorphous solid is a solid in which there is no long-range order of the positions of the atoms unlike those in crystalline solids. An example of an amorphous solid is window glass. In addition many polymers such as polystyrene are amorphous.
Covalent compounds have a lower melting point.

Ionic compounds have a higher melting point.
