Answer 6

Crystalline

Question 7

Class of solid that is easy to break, does so in straight lines

Answer 7

Crystalline

Question 8

Crystalline responds differently to forces, depending on the direction of impact. Different direction, different impact or intensity. What is this called?

Answer 8

Anisotropic

Answer 11

Isotropic

Question 12

When can Amorphous Solids be turned into Crystalline?

Answer 12

by slow cooling their melts
