Explanation:
The particles of perfume diffuse with the air and we get the smell of perfume from a distance. This is possible because the particles of perfume move from the areas of higher concentration to the areas of lower concentration. This process is called diffusion.May 15, 2012
When perfume is released it quickly changes into vapour. The kinetic energy of gas molecules is high & the rate of diffusion is high. Hence we can smell the perfume sitting several metres away.
