1 By comparison, machine shops also cut metal, but they are more concerned with the machining of parts on machine tools. 2  Firms that encompass both fab work and machining are also common. 3  Blacksmithing has always involved fabrication, although it was not always called by that name.
When water is in its solid state (ice) , the water molecules are packed close together preventing it from changing shape. Ice has a very regular pattern with the molecules rigidly apart from one another connected by the hydrogen bonds that form a crystalline lattice.
Clouds can also be composed of ice crystals. (Cirrus clouds) In one case liquid water can freeze to form ice particles. It is more likely that water vapor undergoes deposition, the opposite of sublimation. Sublimation is the process where a solid goes directly to the gas phase without going through the liquid phase.
