Answer 3

Yes. By smell, your nose is merely sensing the molecules of a substance in air. Therefore, to get the "speed of smell" you need to measure the rate of diffusion of the molecules in air.  Some factors that can affect diffusion are size and weight of molecules, humidity, and air currents.

Answer 4

smell will travel with wind and air!
