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

We need to evaluate two statements about fluid properties.

Statement I: "Hot water flows faster than cold water."

This is TRUE. The viscosity of a liquid decreases with increasing temperature because higher kinetic energy of the molecules helps them overcome intermolecular attractive forces more easily. Since viscosity resists flow, lower viscosity means hot water flows faster than cold water.

Statement II: "Soap water has higher surface tension as compared to fresh water."

This is FALSE. Soap is a surfactant that accumulates at the water surface and disrupts the cohesive hydrogen bonds between water molecules, thereby reducing the surface tension. Fresh water has a surface tension of about $$0.073$$ N/m at room temperature, and adding soap lowers this value significantly. This is precisely why soap helps in cleaning — the reduced surface tension allows water to spread and wet surfaces more effectively.

The correct answer is Option (1): Statement I is true but Statement II is false.
