ii. The solids in which atoms, ions or molecules have random non-repetitive three dimensional arrangements are termed as: (a) Crystals (b) Glasses (c) Alloys (d) Amalgams
Answers
Answer:
(b) Glasses
Explanation:
The resulting materials are called amorphous solids or noncrystalline solids (or, sometimes, glasses). The particles of such solids lack an ordered internal structure and are randomly arranged
Correct option is B.Glasses
Glasses is a non-crystalline, often transparent amorphous solid, that has widespread practical, technological, and decorative use.
The standard definition of a glass (or vitreous solid) is a solid formed by rapid melt quenching. However, the term "glass" is often defined in a broader sense, to describe any non-crystalline (amorphous) solid that exhibits a glass transition when heated towards the liquid state.
Glass is an amorphous solid. Although the atomic-scale structure of glass shares characteristics of the structure of a supercooled liquid, glass exhibits all the mechanical properties of a solid. As in other amorphous solids, the atomic structure of a glass lacks the long-range periodicity observed in crystalline solids.
