Given below are two statements:
**Statement I:** Hot water flows faster than cold water.
**Statement II:** Soap water has higher surface tension as compared to fresh water.
In the light of the above statements, choose the correct answer from the options given below.
Answer: (A) Statement I is true but Statement II is false
**Statement I:** The viscosity of a liquid decreases as its temperature rises, so hot water flows faster than cold water. True.
**Statement II:** Soap (a surfactant) **lowers** the surface tension of water; that is why soap water spreads and wets surfaces better. False.
