General Science (Easy) Physics

Dirty cloths containing grease and oil stains are cleaned by adding detergents to water. Stains are removed because detergent:

Reduced drastically the surface tension between water and oil

increases the surface tension between water and oil

increase the viscosity of water and oil

decreases the viscosity in detergent mixed water

Explanation:

Reduced drastically the surface tension between water and oil

Detergent mixes with water to remove dirt and oil from clothes. Water can't remove oil and dirt from clothes. Detergent cleans by causing a chemical reaction with water to force dirt and debris out of clothing. Detergents work with water to loosen the dirt trapped in the material of clothing and clean them away.
