Question

A crystalline solid are-
(a) changes abruptly from solid to liquid when heated
(b) has no definite melting point
(c) undergoes deformation of its geometry easily
(d) has an irregular 3-dimensional arrangements-

Answer 1

Answer:

I think option a is the right answer

Answer 2

Answer:d) has an irregular 3-dimensional arrangements.

Explanation:

Since crystalline solids have very high boiling and melting points, they won't easily change their state and they have definite melting points and they won't undergo geometric deformation easily but they have an irregular 3-dimensional arrangements.
