Q: What is the effect of temperature on the viscosity of liquids?
Solution:
For most liquids, viscosity decreases with an increase in temperature due to increased molecular motion.
Steps: 6
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 is how hot or cold something is.
Step 3: Realize that when you heat a liquid, the molecules inside it move faster.
Step 4: When 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 most liquids decreases.
