Spreading of scent in the air is due to:
Correct answer: A. Diffusion of gas molecules
- A. Diffusion of gas molecules
- B. Effusion of gas molecules
- C. Volume of gas
- D. Temperatue of gas
Explanation
Diffusion is the mixing of molecules with one another. Molecules of the scent fill the spaces between air molecules and the molecules of air fill the spaces between scent molecules due to diffusion. So, the odor of the scent spreads in the room.

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.
