Question

Jim is in a crowd of people at the mall looking for his girlfriend Tammy, who was supposed to meet him for dinner. Jim realizes Tammy is across the room as he catches a whiff of her overpowering perfume, 'Paris #6'. Which process explains why Jim is able to smell the perfume?

Answer 1

He is able to whiff it because of Diffusion. It's a process in which gasses spread to fit the container in which they are, they diffuse around the storage. Her parfume spreads through the mall and becomes weaker but is still there. He can feel it because the parfume spread and came to him before her.
