Q: What is the effect of pressure on the viscosity of liquids?
Solution:
For most liquids, increasing pressure tends to increase viscosity, although the effect is generally small.
Steps: 6
Show Steps
Step 1: Understand what viscosity means. Viscosity is a measure of how thick or sticky a liquid is.
Step 2: Learn about pressure. Pressure is the force applied to a surface area.
Step 3: Know that for most liquids, when you increase the pressure, the liquid's molecules are pushed closer together.
Step 4: When molecules are closer together, they have more difficulty moving past each other, which makes the liquid thicker.
Step 5: This increase in thickness is what we call an increase in viscosity.
Step 6: Remember that while pressure does affect viscosity, the change is usually small for most liquids.
