Q
Q: If the temperature of a liquid increases, what happens to its viscosity?
Solution:
The viscosity of a liquid generally decreases with an increase in temperature.
Steps: 5
Show Steps
Step 1: Understand what viscosity means. Viscosity is a measure of how thick or sticky a liquid is.
Step 2: Know that temperature affects how molecules in a liquid move. When a liquid gets warmer, its molecules move faster.
Step 3: Realize that faster-moving molecules can slide past each other more easily.
Step 4: Conclude that as the temperature of the liquid increases, it becomes less thick or sticky.
Step 5: Therefore, the viscosity of the liquid decreases when the temperature increases.
