Effusion is the movement of gas through extremely small openings of molecular size into a region of _ pressure.
Correct answer: B. Low
- A. High
- B. Low
- C. Moderate
- D. Same
Explanation
Effusion is the movement of a gas, from a region of high pressure, through an extremely small opening of molecular size into a region of "low"pressure. Hence B.

About Kinetic Molecular Theory
Kinetic molecular theory explains gases as rapidly moving particles separated by large distances, with negligible volume and negligible intermolecular attraction in the ideal model. It relates temperature to average kinetic energy and explains gas pressure, Boyle's and Charles's laws, diffusion, effusion and the conditions under which real gases deviate from ideal behavior.
