What happens to the viscosity of a liquid as temperature increases?
Increases
Decreases
Remains constant
Varies unpredictably
As temperature increases, the viscosity of a liquid generally decreases because the increased thermal energy allows the molecules to move more freely.

Q: What happens to the viscosity of a liquid as temperature increases?
Solution: As temperature increases, the viscosity of a liquid generally decreases because the increased thermal energy allows the molecules to move more freely.
Steps: 6
Step 1: Understand what viscosity means. Viscosity is a measure of how thick or sticky a liquid is.
Step 2: Know that temperature is a measure of how hot or cold something is.
Step 3: Realize that when you heat a liquid, its molecules gain energy and move faster.
Step 4: As the molecules move faster, they can slide past each other more easily.
Step 5: Because the molecules can move more freely, the liquid becomes less thick or sticky.
Step 6: Therefore, as the temperature increases, the viscosity of the liquid decreases.
