[amp_mcq option1=”decreases with increase in temperature” option2=”increases with increase in temperature” option3=”is independent of temperature” option4=”is independent of pressure for very high pressure intensities” correct=”option1″]
The correct answer is: A. decreases with increase in temperature.
The viscosity of a gas is a measure of its resistance to flow. It is caused by the collisions between the molecules of the gas. The higher the temperature, the faster the molecules move and the more collisions they will have. This means that the viscosity of a gas decreases with increase in temperature.
Option B is incorrect because the viscosity of a gas decreases with increase in temperature.
Option C is incorrect because the viscosity of a gas is not independent of temperature.
Option D is incorrect because the viscosity of a gas is not independent of pressure for very high pressure intensities.
