A balloon filled with ethyne is pricked with a sharp pointed needle and quickly dropped in a tank of H2 gas under identical conditions. After a while the balloon will be:
Correct answer: B. Enlarged
- A. Shrunk
- B. Enlarged
- C. Completely collapsed size
- D. Remain unchanged in size
Explanation
When a balloon filled with ethyne is pricked with a sharp pointed needle and quickly dropped in a tank of H2 gas under identical conditions, the balloon will enlarge.This is because the rate of diffusion of H2 is greater than the rate of diffusion of ethyne. Hence, H2 gas diffuses more into the balloon, causing it to enlarge. This mathematical proof :

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.
