Answer 2

Statement-1 : Crystalline solids have long range order.

Statement-2 : Amorphous solids have short range order.

• Both statements are true

• Reason 1 : Regular pattern of arrangement of particles which repeats itself periodically over the entire crystal is known as long range order

•Example of crystalline solids having long range order : Quartz

• Reason 2 : Regular and predictable arrangement of atoms over a short distance, usually with one or two atom spacings is known as short range order

• Example : Glass
