Example when materials are prepared as fluids so they can be moved more easily

A simple, albeit slightly less useful example perhaps, is when a foundry, or individual metalworker, liquefies metal such as iron, aluminum, or steel so that it can be mixed in with specific forging agents or transferred around a workplace. 

In general solids are easier to transport than liquids, but the above metal example is a valid one and the only other one that comes to mind is that of concrete. It is mixed as a liquid and transported as such, but then sprayed or laid down to dry and form a solid surface or filler.

Explanation:

Both gases and liquids are fluids, therefore technically, the gas to liquid stuff does not work. 

In addition to the LN2 and LO2 the opposite guys mention, organic compound gases also are oftentimes created into liquids. LPG is of a composition that it liquefies at low pressures. LNG is gas that's terribly cold in order that it becomes a liquid in order that tons are shipped during a tanker. 

Industrial users additionally build solids into liquids for transport in pipelines. as an example, coal slurries area unit typically used. Coal is ground up into the mud, and mixed with water, and may then be pumped up through pipelines. There are different sorts of slurries, like wood chips/water in paper mills, sand/water mixture in dredging machines.
