Vedclass · Answer

(A) Detergents are surfactants that lower the surface tension of water. When detergent is added to water,it reduces the angle of contact between the cleaning solution and the glass surface. $A$ smaller angle of contact allows the solution to spread more effectively over the surface and penetrate the grease,facilitating its removal. Therefore,the correct reason is that it reduces the angle of contact.

The grease deposited on a glass plate can be easily removed by cleaning the glass with hot water containing detergent powder,because the detergent powder
