What are two types of crystal structures shown by ice at different pressures?
- A Hexagonal and monoclinic
- B Cubic and monoclinic
- C Hexagonal and tetragonal
- D Cubic and hexagonal
Answer & Solution
Correct Answer
(D) Cubic and hexagonal
Step-by-step Solution
Detailed explanation
There are two closely related variants of ice: Hexagonal ice, which has hexagonal symmetry, and cubic ice, which has a crystal structure similar to diamond. Ice is the normal form of ice; ice is formed by depositing vapour at very low temperatures (below 140°K)
