Detergents clean surfaces on the principle of
(A) Floatation
(B) Elasticity
(C) Surface Tension
(D) Viscosity
Detergents clean surfaces on the principle of surface tension. They lower the surface tension of water, allowing it to spread and penetrate more easily into dirt and grease. This helps break down and remove impurities, making cleaning more effective.
