We will continue our work on the growth of ice crystals in clouds. We will discuss the principles of weather modification (cloud seeding) and “hole-punch clouds”. We began to look at how ice crystals, once formed, grow in the atmosphere. Growth from vapor phase. Analogies to drop growth, but many characteristics not really governed by the same diffusion-limited process. What is a liquid?.

Jelly crystals- Solid, liquid or gas? Atomic . arrays that are periodic in three dimensions, with repeated distances are called single crystals. . Single crystal specimens maintain translational symmetry over macroscopic distances (crystal dimensions are typically 0.1 mm – 10 cm).. Topics Of the Chapter:. Intermolecular forces..
