For the flow of gases through a capillary, with increase in temperature, the permeability __________________ as per Knudsen law?
Correct answer: A. Increases
- A. Increases
- B. Decreases
- C. Remain same
- D. Either A. or B.; depends on the gas
Explanation
Knudsen permeability depends on molecular thermal speed, which varies as √T. Therefore, increasing absolute temperature increases the permeability through the capillary.
