A solvent cannot dissolve. You can dissolve a solute in a solvent, e.g. you can dissolve sugar in water - sugar is the solute, and water is the solvent. You cannot dissolve water though.
because CuO IS METAL AND METAL CANNOT DISSOLVE IN WATER
A non-polar substance especially the one that does not react with water... Have you seen a powder not dissolving in water? its possible. take some amount of sulphur and put it in water. it will be floating in water. wont dissolve.
insoluble substance
Generally, warming a solvent (like water), makes it faster (easier) to dissolve a dye.

no, corn starch cannot dissolve in water. The grains (particles) that are in the cornstarch are "suspended" in the water and cannot totally dissolve in the water.
Water.
Yes, but not intentionally. Unless it's been specially treated it will have the saime moisture content as the surrounding air, and moisture is water.
most things dissolve faster in hot water.
Jelly crystals do dissolve in water. They dissolve faster in hot water than cold. The hot water breaks down the Gelatin that makes up the jelly.

Hydrophobic molecules do not dissolve in water. This is because water is hydrophilic. Another way to say this is that lipids, which are nonpolar, cannot dissolve in water, which in polar.
Plant does not dissolve in water so it cannot be a solution
no, because soil cannot completely dissolve into water.
insoluble substance
