Thermal Properties of Matter

1 solved JEE Physics previous year questions on Thermal Properties of Matter, each with the correct answer and a full explanation.

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.
