Water molecules are V-shaped, with the center point having a relative (-) electrical charge and the two end points having a relative (+) electrical charge. For molecules to dissolve in water, they need to have areas on them that are at least somewhat (+) or (-). In the water environment, these molecules attract to the oppositely charged portions of the water molecules. These kinds of molecules are termed "ionic", and the rule is that opposite charges attract.
Fat molecules are made from groups of three long chains of carbon covered in hydrogen. These molecules have no regions of (+) or (-) charge on them, and hence they do not mix into water. Since they are less dense, they float on top of the water.
Things that dissolve in water are termed "hydrophilic" (water loving) and things that don't are termed "hydrophobic" (water fearing). All fats and oils are hydrophobic.

definitely not.
if fats dissolve in water, we won't need any soap to wash the dishes.
fats are hydrophobic, so they would not get near water.
while (fyi) soaps are made up of two parts, one is hydrophylic (water-loving) and the opposite part hydrophobic (water-hating), so the hydrphylic part bonds with water, and the hydrophobic part bonds with fat, making what is called a mycelle (or myselle, i'm not sure bout the spelling). so that's how we wash fats away.

Most fats do not dissolve in water.
