- BAdsorption
- CEmulsification
- DOsmosis
- ENone of the above/More than one of the above
Show answer and explanation
Correct answer: (c) Emulsification
Explanation
A soap molecule has a long hydrocarbon tail that dissolves in grease and an ionic head (–COO⁻Na⁺) that dissolves in water.
The tails gather round grease droplets to form micelles, which stay spread through the water and wash away. Breaking grease into tiny droplets suspended in water is emulsification.
