In a closed room of 1000m 'a perfume boiler is opened up. The room develops a smell. This is due to which property of gases?
Correct answer: A. diffusion
- A. diffusion
- B. viscosity
- C. density
- D. none of the above
Explanation
Diffusion is the net movement of gases from a region of higher concentration to a region of lower concentration. Gases spread due to diffusion down the diffusion gradient.

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.
