MCQ

The coefficient of viscosity for hot air is

✓
Greater than the coefficient of viscosity for cold air
B
Smaller than the coefficient of viscosity for cold air
C
Same as the coefficient of viscosity for cold air
D
Increases or decreases depending on the external pressure

✓

Answer

Correct option: A.

Greater than the coefficient of viscosity for cold air

a
Cold air is significantly more viscous, but the viscosity of air is so low that you'd really never notice it anyway.Hot air feels more viscous, it's probably because hot air tends to have more water vapor in it, and humid air tends to feel thicker.
