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.
You forgot solid... Clouds consist of water which has condensed from a gas to a liquid around a solid particle (dust, smoke, etc.) in the atmosphere. Clouds can also be composed of ice crystals at higher altitudes. So, the individual cloud particles, excluding the tiny solid core, can either be liquid or solid water.
