One way is to cool the fluid (liquid) below its Curie point of cooling and keeping the same pressure. The liquid would convert into a solid state which could now be turned into a powder by grinding. However, this may work only for Newtonian fluids. (Ice powder, which is a powder of water, is an example of a liquid turned to powder.) Within industry today, the typical method of turning liquids into powder is by "spray drying" a slurry of water with a suspended solid. Using heat to drive off the water, the resulting precipitate falls as a powder into a collecting bag. (Suspensions of silica is an example of a slurry which, when turned to powder, is then used as a filler in tire rubber.) A new, and little known variation of spray drying, is "pulse drying" whereby super-heated air is "pulsed" at the slurry. This new process is also variable, so that the particle characteristics of the powder can be altered during drying.
Yes. The operators of ski resorts do it all the time.
(If it's not obvious, I'm talking about snow.)
no once the concrete gets hard it cannot turn into liquid state again but you can turn concrete powder into liquid by adding water :)
Allow the steam to cool down and it will turn back to water.
You can turn steam back into water by condensing it, condensation is a process which changes a gas into water.
put ballon on nozzle, turn water on
The movement of the wind/water is used to turn a propeller - this in turn drives an electric generator.
Yes, but if you add too much powder the solution will turn out "supersaturated" and you will be able to see the powder sitting at the bottom.

It doesn't. The solution produced is colourless.
Cuz it's copper sulphate
The best process for separating powder from water depends on the powder. If the powder dissolves in the water, then boiling the water and condensing it (distillation), will separate the two components. If the powder does not dissolve in the water, then simple filtration will separate the two.
Iron powder is not soluble in water.
Talcum powder is insoluble in water.
evaporate it
Synthetic magnesium silicates are insoluble in water or alcohol.
Coffee powder is partially soluble in water.
Red cabbage powder is a natural acid-base indicator. It contains a compound that changes color when exposed to varying concentrations of hydrogen and hydroxide ions. When citric acid and water are added to the powder, the hydrogen ions from the acid interact with a chemical in the red cabbage powder, giving it a purple color.
When making lemonade from powder, the solvent is water.
