Which of the following statements about the viscosity of liquids is true?
Correct Answer: Viscosity generally decreases with an increase in temperature.
- Step 1: Understand what viscosity means. Viscosity is a measure of how thick or sticky a liquid is.
- Step 2: Know that temperature can affect viscosity. When a liquid is heated, its molecules move faster.
- Step 3: Realize that as the molecules move faster, they can slide past each other more easily.
- Step 4: Conclude that when the temperature increases, the viscosity of the liquid usually decreases, making it less thick.
