Strategy:
 Analyze the physical changes in entropy and bonding to deduce the sign of the enthalpy change for adsorption and micellization.

Step 1: Adsorption ()
Adsorption involves the binding of molecules to a surface, which is an energy-releasing process (bond/attraction formation).
Result: .

Step 2: Micelle Formation ()
The formation of micelles is entropy-driven (hydrophobic effect). The process of removing non-polar chains from water and aggregating them typically requires a small amount
