Question: What happens to the viscosity of gases with an increase in temperature?

Options:

Correct Answer: Increases

Solution:

The viscosity of gases increases with an increase in temperature due to increased molecular motion.

What happens to the viscosity of gases with an increase in temperature?

Step 1: Understand what viscosity means. Viscosity is a measure of how thick or sticky a fluid is.
Step 2: Know that gases are made up of tiny particles (molecules) that move around.
Step 3: When the temperature increases, the energy of the gas molecules also increases.
Step 4: With more energy, the gas molecules move faster and collide with each other more often.
Step 5: These faster-moving molecules create more resistance to flow, which means the gas becomes more viscous.
Step 6: Therefore, as the temperature goes up, the viscosity of gases increases.

Viscosity of Gases – The measure of a gas's resistance to flow, which increases with temperature due to enhanced molecular motion.
