Crystalline solids do not have a sharp melting point.

TRUE

FALSE

Answers

Answer:

False

Explanation:

A crystalline solid has a well ordered structure. The particles that make up the solid are arranged in a regular repeating pattern. When the solid is heated, this structure gives way, in order words, the solid melts.

Pure solids crystals are known to have sharp melting points. This is a property of crystalline solids.

The statement about “Crystalline solids do not have a sharp melting point” is false. Crystalline solids are solids that have particles arranged in a regular, repeating patterns. They are held together by uniform intermolecular forces. The faces intersect at a specific angle that identifies that substance. They have distinctive internal structures that in turn lead to distinctive flat surfaces. These flat surfaces give a short rage order. When exposed to x – ray diffractometers, they exhibit a distinctive pattern used to identify the material. They give the same face when you turn a crystalline solid around
