Questions & Step-by-Step Solutions

What is the effect of temperature on the viscosity of liquids?
  • 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.
