**Viscosity** of most liquids with rising temperature:

  1. Increases
  2. Decreases
  3. Stays constant
  4. First increases then decreases
Show answer and solution

Correct answer: B. Decreases

**Liquids:** viscosity ↓ with T (molecules farther apart, cohesive forces weaker). **Gases:** viscosity ↑ with T (faster molecules, more collisions). Important distinction!
