What is the effect of increasing temperature on the viscosity of a liquid?

Step 1: Understand what viscosity means. Viscosity is a measure of how thick or sticky a liquid is.
Step 2: Think about temperature. When you heat a liquid, its temperature increases.
Step 3: Consider what happens to the molecules in the liquid when it gets hotter. The molecules move faster and have more energy.
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 generally leads to a decrease in its viscosity.
