Question: If the temperature of a liquid increases, what happens to its viscosity?

Options:

Correct Answer: Decreases

Solution:

The viscosity of a liquid generally decreases with an increase in temperature.

If the temperature of a liquid increases, what happens to its viscosity?

If the temperature of a liquid increases, what happens to its viscosity?

Step 1: Understand what viscosity means. Viscosity is a measure of how thick or sticky a liquid is.
Step 2: Know that temperature affects how molecules in a liquid move. When a liquid gets warmer, its molecules move faster.
Step 3: Realize that faster-moving molecules can slide past each other more easily.
Step 4: Conclude that as the temperature of the liquid increases, it becomes less thick or sticky.
Step 5: Therefore, the viscosity of the liquid decreases when the temperature increases.

Viscosity and Temperature Relationship – As temperature increases, the kinetic energy of the molecules in a liquid increases, leading to a decrease in viscosity.
