Questions & Step-by-Step Solutions

What is the effect of temperature on the viscosity of a liquid? (2020)
  • 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, its molecules move faster.
  • Step 4: When the molecules move faster, they can slide past each other more easily.
  • Step 5: As a result, the liquid becomes less thick or sticky, which means its viscosity decreases.
  • Step 6: Therefore, when the temperature of a liquid increases, it flows more easily.
