Question

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 of the above statements, choose the correct answer from the options given below:

• A. Statement-I is false but Statement II is true
• B. Statement-I is true but Statement II is false
• C. Both Statement-I and Statement-II are true
• D. Both Statement-I and Statement-II are false

Hint:

Hot water flows faster than cold water due to its lower viscosity, and soap reduces the surface tension of water.

Answer 1

The Correct Option is B

- Statement-I: The hot water flows faster than cold water. 
This is true because hot water has lower viscosity compared to cold water. Lower viscosity allows the fluid to flow more easily. 

- Statement-II: Soap water has higher surface tension as compared to fresh water. 
This is false. Soap water has a lower surface tension than fresh water. Soap acts as a surfactant, which reduces the surface tension of water. Thus, the correct answer is: \[ \boxed{2}. \]
