What is the effect of increasing temperature on the viscosity of liquids? (2019)

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, increasing the temperature of a liquid makes it flow more easily.
