Question: What happens to the viscosity of a gas as temperature increases?
Options:
Viscosity decreases
Viscosity increases
Viscosity remains constant
Viscosity fluctuates
Correct Answer: Viscosity increases
Solution:
For gases, viscosity increases with an increase in temperature due to increased molecular activity and collisions.

Questions & Step-by-Step Solutions
What happens to the viscosity of a gas as temperature increases?
Correct Answer: Viscosity increases.
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: Realize that when the temperature increases, the energy of these gas molecules also increases.
Step 4: As the energy increases, the molecules move faster and collide with each other more often.
Step 5: These more frequent collisions make it harder for the gas to flow smoothly.
Step 6: Therefore, as temperature increases, the viscosity of the gas increases.
Viscosity of Gases – The relationship between temperature and viscosity in gases, where viscosity increases with temperature due to heightened molecular activity.
