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.
Liquid is just one of the several states of matter. Along with solids and gas, liquid is the middle phase with regard to the phases of water change (from ice, to melted ice, and then to water vapor). A solid ice cube becomes water because of melting. Melted water turns to water vapor because of evaporation.
