Which statement explains the cleaning action of soap on greasy dishes?

#SCPH05 I Biotechnology

  1. The soap changes the water-solubility of the grease so that it is easily dissolved by the water.

  2. The grease is trapped inside the hydrophobic interior of micelles made of soap molecules.

  3. The soap chemically breaks down the grease into smaller, more water-soluble molecules.

  4. The soap hydrates the grease with its polar head groups and holds it in suspension.
