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.
The cloudâs essential component, water, can be found in all three states; in addition to droplets of liquid water, clouds contain water in its gaseous form, called water vapor, and in cold weather, they can become frozen into solids. [2] How Do Clouds Form? Clouds are a combination of water droplets and condensation nuclei. Clouds are formed when evaporation pulls water into the air creating the gaseous form of water called water vapor. When the air becomes saturated, water vapor condenses into liquid water droplets. However, it takes more than gaseous water vapor and liquid water droplets to form a cloud. These water droplets require condensation nuclei to condense upon such as dust, pollen, or smoke.
