Question
Physics Question on mechanical properties of fluid
Coefficient of viscosity of a gas
A
increases with increase of temperature
B
decreases with increase of temperature
C
remains constant with increase of temperature
D
may increase or decrease with increase of temperature.
Answer
increases with increase of temperature
Explanation
Solution
With increase in temperature, the molecule of gas carry more momentum and collide more often, that means more viscosity. So, coefficient of viscosity of a gas increases with increase of temperature.
