Q: Which of the following is CORRECT about the viscosity of gas?
  • A. Inversely proportional to the temperature
  • B. Increases with an increase in the temperature
  • C. Independent of pressure
  • D. Independent of temperature
Correct Answer: Option B - Viscosity of gases increases with the increase in temperature. The viscosity of gases near room temperature are in the centipoise range, so that is a commonly used unit. Whereas the viscosity of liquid decreases with the increase in temperature
B. Viscosity of gases increases with the increase in temperature. The viscosity of gases near room temperature are in the centipoise range, so that is a commonly used unit. Whereas the viscosity of liquid decreases with the increase in temperature
