Q: What is the relationship between temperature and viscosity for most 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 is. 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, the molecules inside it start to move faster.
Step 4: Recognize that faster-moving molecules can slide past each other more easily.
Step 5: Conclude that as the molecules move more easily, the liquid becomes less thick or sticky.
Step 6: Therefore, for most liquids, when the temperature goes up, the viscosity goes down.
