increases
decreases
remains unaffected
unpredictable
Answer is Right!
Answer is Wrong!
The correct answer is B. decreases.
The dynamic viscosity of a gas is a measure of its resistance to flow. It is inversely proportional to the temperature, which means that as the temperature increases, the viscosity decreases. This is because the molecules in a gas have more energy at higher temperatures, and they are able to move around more freely. This makes it easier for them to slide past each other, and the gas becomes less viscous.
Option A is incorrect because the viscosity of a gas decreases with increasing temperature. Option C is incorrect because the viscosity of a gas is not unaffected by temperature. Option D is incorrect because the viscosity of a gas is not unpredictable.
