Question

Given below are two statements : Statement (I) : Viscosity of gases is greater than that of liquids. Statement (II) : Surface tension of a liquid decreases due to the presence of insoluble impurities. In the light of the above statements, choose the most appropriate answer from the options given below :

G1 Physics · Accepted Answer

Gases have less viscosity than liquids, so Statement I is incorrect. Insoluble impurities such as detergent decrease the surface tension of a liquid, so Statement II is correct. Correct option: B.
