Question 8 • IA-Chemistry A Survey of Chemistry A

A group of students are wandering around a room. When their teacher claps, the students sit down wherever they are.This situation best models the formation of which type of solid?

Answer
A
an amorphous solid because the particles do not have a regular structure
B
an amorphous solid because the motion of the particles stopped
C
a crystalline solid because the moving particles lock into fixed positions
D
a crystalline solid because the particles have a long-range order

Explanation

The students sit wherever they happen to be, so their positions do not form a repeating, orderly pattern. That models an amorphous solid, whose particles lack a regular structure. Simply stopping their motion does not make a solid crystalline; crystalline solids have particles arranged in long-range order.
