Question

Why is essential to vigorously agitate dirty clothes with liquid soap in water, why not just let the soap soak into the dirt and then rinse it off? Choose the TWO best answers.

- Soaking the dirt with liquid soap does not allow the micelles to form, but rather just coats the dirt.
- Vigorous agitation breaks up the fatty acids into micelles that are then rinsed away with the dirt inside.
- Agitation helps the dirt gets loose and fall off, whereas the soap is simply there to make the material more flexible.
- The problem with soaking is that the soap dries out and gets crusty, whereas agitation creates lots of bubbles.
- Agitation provides for energy conversion between potential energy and entropy, whereas soaking is enthalpy.
- Soaking is the best way to liquify the dirt and agitation is a good way to break hydrogen bonds with water.
- Agitation makes the fabric lose it color and the micelles that form retain the color, so agitation is important.

Answer 1

It is essential to vigorously agitate dirty clothes with liquid soap in water because it helps break up the dirt and oils into tiny soap-enclosed droplets called micelles, which disperse throughout the solution. These micelles are then rinsed away with the dirt, ensuring a more effective cleaning process.

Step-by-step explanation:

The reason it is essential to vigorously agitate dirty clothes with liquid soap in water instead of just letting the soap soak into the dirt and then rinsing it off is because of the properties of soap molecules. Soap molecules have a dual nature, with one end attracting to water and the other end attracting to oils and dirt. When you agitate the clothes, it helps break up the dirt and oils into tiny soap-enclosed droplets called micelles, which disperse throughout the solution. These micelles are then rinsed away with the dirt, ensuring a more effective cleaning process.

Vigorous agitation breaks up the fatty acids into micelles that are then rinsed away with the dirt inside. This process helps to remove dirt particles that have stuck to the fabric and ensures a more thorough cleaning.
