I’m not sure what it means :/

answer: 1.)Two fluid technologies that make use of air is a desk chair and air compressor

2.)Two fluid technologies that make use of water is a fire extinguisher and refrigerator

3.)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.

4.)It is important to go through a fluid phase as it is being produced because the object must go through heat to be melted and then it should be put into a mold to be formed. Also, it go though heat to keep it from cracking and go to be cooled and harden.
