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 above statements, choose the correct answer from the options given below [JEE Main 2025, 23 Jan (Shift 1)]
aBoth Statement I and Statement II are false
bStatement I is false but Statement II is true
cBoth Statement I and Statement II are true
dStatement I is true but Statement II is false
✓ Correct answer: d) Statement I is true but Statement II is false
ExplanationThe viscosity of water decreases with increasing temperature, allowing hot water to flow more easily than cold water.Adding soap to water reduces surface tension because soap molecules disrupt the cohesive forces between water molecules.
