Question

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

• A. Both Statement 1 and Statement 2 are true, and Statement 2 is the correct explanation of Statement 1.
• B. Both Statement 1 and Statement 2 are true, but Statement 2 is not the correct explanation of Statement 1
• C. Statement 1 is true, but Statement 2 is false
• D. Both Statement 1 and Statement 2 are false

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.

Answer 1

The Correct Option is C

- 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.
