Question:

$\text{An example of amorphous solid among the following is -}$

Options:

1. $\text{Graphite (C)}$
2. $\text{Quartz glass (SiO}_2\text{)}$
3. $\text{Chrome alum}$
4. $\text{Silicon carbide (SiC)}$

Solution:

$\text{HINT: Atoms and molecules are not organized in a definite lattice pattern.}$ $\text{Explanation:}$ $\text{Unlike a crystalline solid, an amorphous solid is a solid that lacks an ordered internal structure. Some examples of amorphous solids include rubber, plastic, and gels.}$ $\text{Quartz glass (SiO}_2\text{) is an amorphous solid due to its short-range order of constituent particles. It is formed by fusing the crystal and then cooling it rapidly.}$ $\text{Quartz glass is amorphous solid because it is formed by fusing the crystal and then cooling it rapidly. Crystalline solids have regular ordered arrays of components held together by the uniform intermolecular forces, whereas the components of the amorphous solid are not arranged in the regular arrays.}$
