how does soap exhibit its cleansing property?

Question

Answer 1

Soap is a molecule that consist of long carbon chain ending in -COONa. The latter endchain easily attaches to water and the carbon chain attaches to fats and grease. Although grease will normally adhere to skin or clothing, the soap molecules can attach to it as a "handle" and make it easier to rinse away.

Answer 2

Soap changes the surface tension properties of water, making them slicker. Notice when you put a drop of water on a slick painted surface of a car. It beeds due to the wax on the car. Add a minute amount of soap to that beed of water and it will flatten out. You'll also notice that super glue will not dry nearly as fast if a drop is placed on wax paper. The surface tension keeps the glue from drying as fast so that you can apply it easier to your project without being rushed to do the task.
