  1. Heating a fluid
  2. Cooling a fluid
  3. Adding a solvent
  4. Increasing pressure

Questions & Step-by-Step Solutions

In which of the following scenarios does viscosity increase?
  • Step 1: Understand what viscosity means. Viscosity is a measure of how thick or sticky a fluid is.
  • Step 2: Know that temperature affects viscosity. Generally, when a fluid is cooled, it becomes thicker.
  • Step 3: Remember that as a fluid cools, its molecules move slower and stick together more, which increases viscosity.
  • Step 4: Conclude that viscosity increases when a fluid is cooled.
