Viscosity & Stokes' Law
Given below are two statements:
Statement I: The hot water flows faster than cold water
Statement II: Soap water has higher surface tension as compared to fresh water. In the light above statements, choose the correct answer from the options given below
Show answer and solution
Answer: (d)
- Statement I: viscosity of a liquid decreases with temperature, so hot water flows faster. True.
- Statement II: soap (detergent) lowers the surface tension of water. False.
- So the answer is (d) Statement I is true but Statement II is false.
