A chef in restaurant baking 2 different desserts in the oven . He removes a pumpkin and some chocolate chip cookies at the same time from the oven . The smell of cookies reaches you a minute before you smell the pie. Since the particles have the same temperature , the smell of cookies reaches you first because.

the air molecules from the cookies diffused faster than the air molecules from the pumpkin

Explanation:

The smell of cookies reaches first because the air molecules from the cookies were able to diffuse faster than the air molecules from the pumpkin.

At constant temperature, the diffusion rates of two molecules would be dependent on the size of the molecules. The bigger the size of the molecule, the more time it will take for the molecule to diffuse and vice versa.

Thus, since the pumpkin and the cookies were baked at the same temperature, the smell of the cookies was perceived first because the air molecules of the cookies are smaller in size than the air molecules of the pumpkin.
