Question

what is different between Crystalline solid and Amorphous solid. ​

Answer 1

Answer:

Crystalline solids have well-defined edges and faces, diffract x-rays, and tend to have sharp melting points. In contrast, amorphous solids have irregular or curved surfaces, do not give well-resolved x-ray diffraction patterns, and melt over a wide range of temperatures

Answer 2

Answer and Explanation:

$\blacksquare$ $\huge \text{\boxed{\boxed{\mathbb{CRYSTALLINE \ \ SOLIDS}}}}$

$\diamond$ Regular arrangement of molecules are present

$\diamond$ Long range order

$\diamond$ Sharp melting and boiling point

$\diamond$ Anisotropic

$\diamond$ True solids

$\diamond$ Symmetrical

$\diamond$ Can be perfectly cut with a knife

$\diamond$ Examples are : Potassium nitrate (KNO₃) and copper (Cu)

$\blacksquare$ $\huge \text{\boxed{\boxed{\mathbb{AMORPHUS \ \ SOLIDS}}}}$

$\diamond$ Irregular arrangement of molecules are present

$\diamond$ Short range order

$\diamond$ No particular melting or boiling point

$\diamond$ Isotropic

$\diamond$ Pseudo or false solids

$\diamond$ Assymmetrical

$\diamond$ Cannot be perfectly cut with a knife ie, produces irregular edges

$\diamond$ Examples are : PVC, cellophane
