Question:

Statement 1: Hotter water moves faster than cold water.
Statement 2: Soap water has a higher surface tension than fresh water.

Show Hint

Remember, increasing temperature increases the molecular motion, so hotter water will move faster. Soap generally lowers surface tension, making it easier for water to spread and form bubbles.

The Correct Option is C

Solution and Explanation

- Statement 1: Hotter water moves faster than cold water. This is true because as the temperature of water increases, the molecules gain more kinetic energy and move faster. - Statement 2: Soap water has a higher surface tension than fresh water. This statement is false. Soap reduces the surface tension of water rather than increasing it. Thus, Statement 1 is true, but Statement 2 is false.
