They are called an Emulsion. Although the terms colloid and emulsion are sometimes used interchangeably, emulsion tends to imply that both the dispersed and the continuous phase are liquid.
I'm not sure what your asking but the term for substances that are unable to dissolve in water are called unsoluable.
Due to the density of the oil it is unable to dissolve a lolly
saturated
a liquid gets saturated when it is unable to dissolve further solute in it..
When a substance is unable to dissolve into a solvent, it will remain as a separate phase or form a suspension or precipitate. In other words, it will either float or sink in the solvent, or it will form small solid particles that do not dissolve. Examples include oil and water, where oil does not dissolve into water but forms separate droplets or layers.
There are plenty of metals that will dissolve given the correct solvent or solvents combined. Google "royal water"
the solute becomes so tiny we are unable to see them with our naked eyes
solids - tightly packed and unable to move liquids- tightly packed but able move gases- spread out and able to move
Materials like salt and sugar will dissolve in the water and are called soluble as they dissolve completely in the water, where as substances that do not dissolve in water like sand are called insoluble materials.
I am unable.
Immortal.
Another common word for can't is the word "unable". To be unable is the act of not being able to accomplish a task.
