Q. Why do detergents clean oily clothes effectively?
Answer: They decrease surface tension of water
Notes: Detergents are surfactants that lower water's surface tension, letting water spread and penetrate fabric. This allows the emulsification and removal of oily dirt from clothes, making cleaning efficient. Surfactants disrupt water molecules, reducing cohesion at the surface.
