Soap

Soap is an ordinary household item that is mainly used for washing dishes, scrubbing floors, doing laundry, bathing, and many other household tasks. Soap can also be used by doctors to get rid of germs in infected wounds. It comes in many different forms such as a liquid, a powder, or a bar. It also comes in different scents to suit the consumer and the task for which it is needed. Soap is actually a base with a fat. The soap that is usually used for bathing is only varies from laundry detergent in that it has different chemical properties. A chemical property that they do have in common, however, is a surface active agents. Surfactants are molecules that stick to bits of dirt in a material. Then, the molecules hold the bits of dirt in the wash water until they are rinsed off. The chemical composition of soap in general is what causes it to have its particular density. Density is the measure of the mass of the substance divided by its volume. Soap, particularly solid Ivory™ soap, has a density of 0.9 grams per cubic centimeters. Dawn™ liquid soap has a density of 0.932 g/cm3. From this information, you could see that the density does not significantly change as the soap varies from solid to liquid. In conclusion, this shows that soap is unlike any other substances because it is widely known that solids generally have a different density than liquids.
